scan agent timed out on infinite scroll content load - how to fix it

TL;DR

Cap the scroll: scroll until no new content appears for N consecutive attempts or a max-scroll budget is hit, then scan what loaded. Infinite scroll never settles, so the agent must define done. One line of why: waiting for network quiet on an infinite feed is waiting forever, the agent needs its own termination condition.

The error, verbatim

ScanAgentError: timed out waiting for infinite scroll to settle after 180s
    url: https://example.com/feed
    scrolls: 47, new_content_last_seen: scroll 12

Fix it step by step

Step 1: Reproduce the endless scroll

node agent/run-audit.js --route /feed | rg -i 'scroll|timed out' | head -5

Expected: The agent scrolls until its timeout fires.

Step 2: Confirm content stopped arriving

node -e "console.log('check: after scroll 12 no new nodes appeared, the agent kept scrolling anyway')"

Expected: The log shows new content stopped long before the timeout.

Step 3: Add the settle condition

rg -n 'scroll' agent/scanner.js | head -10

Expected: Add: stop after 3 scrolls with no new nodes or 25 scrolls max, then scan.

Step 4: Re-run the audit

node agent/run-audit.js --route /feed | tail -4

Expected: Agent stops scrolling at the settle point and audits the loaded content.

Step 5: Add a regression probe

node agent/run-audit.js --smoke | tail -3

Expected: Smoke run passes; schedule it so the breakdown is caught if it ever regresses.

When to use this skill

• You run an agent that scans UIs for accessibility and it hits this breakdown
• The agent's scan loop stalls, crashes, or loops on this exact failure
• You are hardening an audit agent's error handling for production scans

When NOT to use this skill

• A human runs the scan manually and it works, this is agent-harness failure handling
• The scan completes and only reports violations, use the rule-specific skills

Compatibility

Scan agent harness with scroll primitives. The settle condition is consecutive no-new-content scrolls plus a max budget. Pin the tool version in the lockfile so scans stay reproducible across machines.

Variant phrasings

agent infinite scroll timeout

Same failure, same settle condition.

scan never finishes on feed page

Practitioner phrasing.

the breakdown hits other routes too

Agent failure modes are systemic; apply the hardening to every route the agent covers, not just the one that failed.

Why it happens

Infinite scroll pages load more content as long as the agent scrolls, so any wait-for-settle strategy never settles. Agents that scroll-until-quiet loop until their global timeout. The correct termination is content-based: track node count or item count per scroll, stop after a few scrolls with no growth, and cap total scrolls regardless. The audit then covers a representative sample, and the agent reports how much content it covered. Agent breakdowns are systemic: the same failure mode will hit every route, page, or run the agent touches. Harden the harness once (timeouts, loop detection, verification gates) instead of patching per page, and keep breakdown telemetry separate from violation counts.

Edge cases

• Report the coverage (items loaded vs estimated total) as audit metadata, a partial audit should say so.
• Virtualized feeds unload off-screen content, scrolling back up loses nodes, snapshot per viewport instead.
• Some feeds load on a timer without scrolling, the no-new-content counter handles those too.
• Log breakdowns separately from violations in agent telemetry; mixing them hides whether the agent itself is getting more reliable.

RSS agent timed out waiting for infinite scroll results

TL;DR

An RSS agent waiting on infinite scroll is using the wrong tool: infinite scroll is a UI pattern, and the data behind it almost always has a paginated API, a feed, or a sitemap. Do not automate the scroll; find the underlying data endpoint the page itself calls. If none exists, treat the source as unscrapeable for bulk collection and use its feed or API.

The error

(agent timeout)
rss agent timed out waiting for infinite scroll results; scroll loop never finished

When this helps

• an agent times out on infinite scroll
• listing pages never finish loading
• choosing between scrolling and data endpoints
• bounding scroll automation

When it doesn't

• the site offers a proper API; use it instead of any scrolling
• the terms forbid automated collection; skip the source
• you need the full history; scrolling cannot reliably provide it

Works with

Any HTTP client; browser automation only as a capped last resort.

Steps

1. Stop scrolling and look for the page's data API

curl -s -A "IntelBriefingBot/1.0" "https://YOUR-site/sitemap.xml" -o sitemap.xml -w "HTTP %{http_code}\n"
curl -s -A "IntelBriefingBot/1.0" "https://YOUR-site/feed" -o feed.xml -w "feed HTTP %{http_code}\n"

Expected: A sitemap or feed. Infinite-scroll listings are usually backed by one of these for crawlers.

2. Cap any scroll automation as a last resort

import time
MAX_SCROLLS = 10
for i in range(MAX_SCROLLS):
    print("scroll", i + 1, "of", MAX_SCROLLS)
    time.sleep(2)
print("hard cap reached; agent moves on with what it has")

Expected: A bounded loop. If scrolling is ever used, it ends after 10 rounds no matter what.

3. Prefer the site's search or archive pages

curl -s -A "IntelBriefingBot/1.0" "https://YOUR-site/archive/2026/10" -o archive.html -w "HTTP %{http_code}\n"
grep -o "https\?://[^ \"]*" archive.html | sort -u | head -10

Expected: Archive page links. Date archives give the same listing content as the scroll, in one fetch.

4. Record the source as scroll-only if no alternative exists

import json
reg = json.load(open("sources.json"))
reg["https://YOUR-site/listing"] = {"status": "scroll-only", "policy": "fetch first page only"}
json.dump(reg, open("sources.json", "w"), indent=2)
print("scroll-only source: first page only, no bulk collection")

Expected: A registry policy. Scroll-only sources contribute their first page; bulk history comes from feeds or archives.

Other ways people phrase this

infinite scroll timeout scraper

Find the data endpoint behind the scroll. The UI pattern is not a data API.

rss agent scroll loop stuck

Cap the loop hard. Scrolling is the fallback, never the plan.

listing page never finishes loading

Archive or sitemap pages give the same content without the scroll.

Why it happens

Infinite scroll loads content in small batches as the user scrolls, which is hostile to automation: the agent cannot know when it is done, and each batch costs a render cycle. The page's own data API or archive serves the same items deterministically. Scrolling is the site's UI choice, not a collection interface.

Edge cases

• Some sites lazy-load with no backing API; those are scroll-only by design.
• Scroll position affects which items load; automation gets inconsistent slices.
• The backing API may need the page's session; check the page's own requests.
• Respect robots.txt on archive and sitemap paths even when the scroll page is allowed.

TL;DR

Fix this in SharePoint search agent by acting on the exact problem first: search through the SharePoint search index with all name variants in one indexed query per library group, save results per library, and scan libraries in batches, resuming with the first unscanned library after any timeout. Do not rerun the whole job or request unchanged, because the same inputs produce the same failure. Prove the fix on one request, system or batch first, then rerun the full scope and reconcile the counts.

agent timed out scanning document libraries for requester name variants

Use this when

• The operation in SharePoint search agent fails with this exact message or symptom: agent timed out scanning document libraries for requester name variants.
• The same failure repeats on retry with unchanged inputs.
• A privacy request, export, deletion or deadline is blocked until this item completes.

Not for this skill when

• The message is an outage notice from the platform. Resolve that first, then return here if this problem remains.
• The operation completes and you only disagree with a legal interpretation or a policy choice. That is a privacy team decision, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in SharePoint search agent, and copy the full message plus the request, system or record involved into the run notes. Verify: the problem is reproduced on demand with a named scope, not only seen in a log.
2. Apply the specific fix for this problem: search through the SharePoint search index with all name variants in one indexed query per library group, save results per library, and scan libraries in batches, resuming with the first unscanned library after any timeout. Verify: the smallest failing scope now completes, or the named request, system or record behaves as the fix predicts.
3. Check the neighbouring requests, systems or records that share the same connector, mapping or owner, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in SharePoint search agent on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
5. Compare the result counts or status against the source in SharePoint search agent so a silent partial success is caught before the request is closed. Verify: counts match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the request so the next occurrence is recognised immediately. Verify: the record names the problem, the fix applied and the evidence of success.

Why it happens

Opening every library and folder directly scales with total documents, while the search index already holds the text needed to find name variants quickly.

How to fix - agent timed out scanning SharePoint document libraries for requester name variants

The how to phrasing for the same failure in SharePoint search agent. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

SharePoint search agent troubleshooting for this failure

The symptom first phrasing used when the console hides the full message. Surface the full message first, confirm it matches the code block above, then follow the steps.

Edge cases

• If the fix works on the small scope but the full rerun still fails on a different system, treat that system as a new instance, record its scope separately, and apply the same steps rather than widening the first fix blindly.
• If personal data was already sent to the wrong place or a notice was already sent early, record the incident for privacy assessment first, then apply the fix, and note the affected request in the run record.
• If a legal hold or a verification question is in play, pause deletion or delivery for that request only, resolve the hold or verification, and keep other requests moving.

Compatibility: SharePoint search agent at current versions, plus the admin console or API the query names; no extra tooling beyond the source system access needed to verify counts.
