Wellfound scraper session expired logged out

Not specified by the original author.

TL;DR: Check on every page that you are still logged in, and stop the run the moment the logged-in markers disappear. Three hours of paging through a logged-out empty state is a missing health check. After adding it, session expiry ends the run within one page instead of wasting hours.

Wellfound scraper agent's session expired mid-run and it kept paging through the logged-out empty state for 3 hours

1. Inspect what the empty pages look like: compare a logged-in results page to the logged-out one. Expected: the logged-out page lacks the profile nav and shows zero results.
2. Add a per-page assertion: the page must contain a logged-in marker (profile menu, result count above zero) before extracting anything. Expected: the first expired page trips the assertion.
3. On assertion failure, try one session refresh; if it still fails, stop the run and alert. Expected: the run ends within one page of expiry.
4. Re-run after re-authenticating and watch the page count. Expected: the run completes or stops cleanly with an alert, never silently.

Use this when

• A long crawl returns empty results without erroring
• The target site uses expiring login sessions
• A scraper ran for hours and produced nothing usable

Not for this skill when

• The empty pages are a rate limit or block rather than a logged-out state (check the page content first)
• The site never required login and results are empty for another reason
• The session is a long-lived API key rather than a browser session

Variant phrasings

Scraper kept crawling after session expired, empty results

Wellfound session timeout mid-run not detected

Crawler paged logged-out pages for hours

Why it happens

Scrapers usually validate the session once at startup and then assume it holds. Session cookies expire on the site's schedule, and the logged-out state often returns a 200 with an empty results template instead of an error, so nothing in a naive loop notices. The crawler happily pages through nothing until someone looks.

Edge cases

• Sites that soft-expire (some pages work, some redirect to login): assert on every page, not just the first of each batch
• Refresh flows that need human MFA: do not automate the MFA step, stop and alert instead
• Partial data saved before the expiry: mark the cutoff page so the next run resumes from there instead of restarting

TL;DR

Fix this in Label Studio by acting on the exact message first: replace screen scraping with the platform API where one exists, otherwise wait for the data element rather than a fixed delay and detect a login redirect explicitly. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

scraper failed on Label Studio login page after session expired error

Use this when

• The operation in Label Studio fails with this exact message: scraper failed on Label Studio login page after session expired error.
• The same failure repeats on retry with unchanged inputs.
• A review, export or check is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in Label Studio, and copy the full message plus the item, user or metric involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: replace screen scraping with the platform API where one exists, otherwise wait for the data element rather than a fixed delay and detect a login redirect explicitly. Verify: collect two consecutive pages and confirm no login page content appears in the results.
3. Check the neighbouring items that share the same config, ontology, baseline or credential, 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 Label Studio 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, decisions or alerts against the source in Label Studio so a silent partial success is caught before sign off. 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 item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

Scrapers break on session expiry and async rendering; fixed delays and page counts no longer match what the site actually returns.

The how-to phrasing for the same failure in Label Studio. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

Label Studio 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.

Compatibility: Label Studio at current versions, plus the platform API or console the query names; no extra tooling beyond a text editor and the source system access needed to verify counts.

auth token expired mid vendor portal scrape and failed to resume: how to fix it

An auth session expiring mid vendor portal scrape needs the scraper to detect expiry and re-authenticate, then resume from its checkpoint. Add session checks between pages and a login routine. Long scrapes always outlast short sessions.

auth token expired mid vendor portal scrape and failed to resume

When to use this skill

• Scrapes die on expired auth mid-crawl
• Resume attempts fail on the dead session

When not to use this skill

• Login itself fails (an auth issue)
• The portal blocks the scraper (an access issue)

Tool compatibility

Agent portal scraping with session auth. Related area: auth sessions, SSO, and identity flows. Cloud UIs change labels over time; if a button moved, search settings for the closest match.

Before you start

• Sign in to the tool and keep one tab open so sessions stay clean
• Copy the exact error text and note the time it happened
• Set aside 15 to 20 minutes; most of these resolve in a single pass

Quick diagnosis

Make sure this is the right skill before you invest the 15 minutes.

• If you are dealing with scrapes die on expired auth mid-crawl, start at step 1 below.
• If instead login itself fails (an auth issue), stop here; you need a different skill.
• If neither quite matches, compare your screen against the verbatim error block at the top; that block is exactly what this skill covers.

Fix it in steps

1. Check session health per page

Verify the session before each page fetch.

Expected: expiry detected before a wasted request.

2. Build an automated re-login

Re-authenticate programmatically when the check fails.

Expected: a fresh session without manual help.

3. Resume from the checkpoint

Continue the crawl from the last saved page.

Expected: no repeated or skipped pages.

4. Test with short sessions

Force an expiry mid-crawl in testing.

Expected: clean recovery.

Confirm each step worked

Run through this checklist before moving on. If a check fails, redo that step instead of pushing ahead.

• Step 1 (check session health per page): Expected: expiry detected before a wasted request.
• Step 2 (build an automated re-login): Expected: a fresh session without manual help.
• Step 3 (resume from the checkpoint): Expected: no repeated or skipped pages.
• Step 4 (test with short sessions): Expected: clean recovery.

Quick recap

1. Check session health per page
2. Build an automated re-login
3. Resume from the checkpoint
4. Test with short sessions

Still stuck?

Gather three things: the exact error text, the time it happened, and what changed just before it broke. Check the vendor status page for an active incident. Then open a support ticket with those three things; it cuts the back-and-forth in half. For agent runs, attach the last 50 lines of the agent log too, since the loop or timeout signature in the log usually names the cause.

Variant phrasings

session expired mid scrape

Health checks plus auto re-login. If this matches what you saw, the steps above apply as written.

scraper failed to resume after expiry

Resume from checkpoint, not from scratch. If this matches what you saw, the steps above apply as written.

Why it happens

Portal sessions expire on idle and absolute timers while crawls run long. A scraper that authenticates once has no recovery when the session dies, and naive retries reuse the dead session.

Edge cases

• MFA on re-login complicates automation, plan the handoff
• Checkpoint every page so resume is exact
• Log session age to predict expiry
