alt text in email error outlook strips alt on blocked images bug

Not specified by the original author.

TL;DR

Fix this in Freshdesk by acting on the exact symptom first: add the alt text in the article HTML view after uploading the image, save, and recheck the published page source, because the visual editor upload path drops the attribute on insert. Do not repeat the same edit, search or run unchanged, because the same inputs produce the same failure. Prove the fix on one article, collection or query first, then apply it across the affected scope and confirm as a reader.

Freshdesk article image alt text is stripped, failing accessibility audit checks

Use this when

• Work in Freshdesk shows this exact symptom: Freshdesk article image alt text is stripped, failing accessibility audit checks.
• The same symptom repeats after a retry with unchanged inputs.
• Readers or support agents are blocked until this item is corrected.

Not for this skill when

• The help center platform itself is down or returning outage notices. Resolve that first, then return here if this symptom remains.
• The content is correct and you only want a style or tone rewrite. That is an editorial pass, not this fix.

Steps

1. Reproduce the symptom with the smallest scope that still shows it in Freshdesk, and record the article, collection or query involved plus the exact wording from the code block above. Verify: the symptom is reproduced on demand with a named scope, not only reported second hand.
2. Apply the specific fix for this symptom: add the alt text in the article HTML view after uploading the image, save, and recheck the published page source, because the visual editor upload path drops the attribute on insert. Verify: the smallest failing scope now behaves as the fix predicts, checked in the published view rather than only in the editor.
3. Check neighbouring articles, collections or locales that share the same template, category or workflow, because this class of problem rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Repeat the original reader or agent action in Freshdesk that exposed the symptom, using the same query, link or workflow as the first attempt. Verify: the action completes and the original symptom does not appear.
5. Compare the result against the source of truth for this item, the current product behaviour, price list, release notes or ticket evidence named in the fix. Verify: the published result matches the source or every difference is named and explained.
6. Record the fix, the scope it covered and the verification result where the content team works, so the next occurrence is recognised immediately. Verify: the record names the symptom, the fix applied and the evidence of success.

How to fix - Freshdesk article image alt text stripped failing accessibility audit checks

The how to phrasing for the same problem in Freshdesk. The steps above apply unchanged; start at the reproduction step rather than skipping to the final check.

Freshdesk troubleshooting for this symptom

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

Why it happens

The editor inserted images without carrying the alt attribute into the saved markup, so screen readers and audits found images with no description at all.

Edge cases

• The symptom appears in one locale, collection or audience view only. Fix that scope, then check the same item in the other views before closing.
• A cached or indexed copy keeps showing the old state after the fix. Allow for the platform reindex or cache window, recheck in a fresh reader session, and only then escalate.
• Two items have near identical titles. Confirm the identifier of the item you edited, not just its title, before declaring the fix verified.

Compatibility: Freshdesk at current versions, plus the help center admin, search or API surface the query names; no extra tooling beyond reader level access to verify the published result.

Fix email template renderer breaking the onboarding agent on a missing merge tag

TL;DR

The renderer fails the whole send when one merge tag has no value. Give every tag a default or make missing tags non-fatal, and validate the data before rendering. One empty field should not kill a welcome email.

The error

Onboarding agent failed
Email template renderer broke on missing merge tag: first_name.

Use this skill

Agent? Search Vectle for this error:

curl -s "https://vectle.com/api/v1/search?q=email template renderer broke and onboarding agent failed on missing merge tag"

Fix it

Step 1: Identify the missing tag

Read the error for the tag name and check the user record.

Expected: You confirm the field is empty for this user.

Step 2: Add defaults for all tags

Give every merge tag a sensible fallback in the template.

Expected: Missing data renders as the default instead of failing.

Step 3: Validate data before rendering

Check required fields exist before calling the renderer.

Expected: Bad records are quarantined with a clear reason.

Step 4: Make the renderer non-fatal on missing tags

Configure the renderer to warn and continue rather than throw.

Expected: One missing tag never kills a send again.

Step 5: Re-run the welcome send

Retry the failed email.

Expected: It sends with defaults in place of the missing value.

When this applies

• Template rendering fails on missing merge tags
• Welcome emails die for users with incomplete profiles
• You are building templated email agents

When it doesn't

• The template syntax itself is broken (fix the template)
• All tags are missing (check the data source)
• The email sends but looks wrong (check the template logic)

Compatibility

Template renderers generally: Handlebars, Liquid, Jinja-style, and others.

Variant phrasings

missing merge tag email render failed

Same failure. Defaults plus non-fatal rendering fixes it.

template variable undefined email agent

Undefined variables should degrade, not crash. Set that behavior explicitly.

welcome email failed empty field

Empty profile fields are normal for new users. Templates must handle them.

Why it happens

Templates reference user fields that are not always populated, especially for brand-new users. Strict renderers throw on the first missing value, and the agent treats it as a fatal send failure. The data gap is expected; the renderer's strictness is the bug.

Edge cases

• Defaults must be sensible per tag; a wrong default is worse than a blank
• Quarantined records still need the email eventually; alert, do not just skip
• Test templates against a minimal user record with every optional field empty

If it still fails

• Reproduce with a minimal run: one user, one file, one step.
• Read the agent's full trace, not just the final error; the failure is usually upstream.
• Check the underlying API or tool directly, outside the agent, to separate agent bugs from service bugs.
• Reduce concurrency to one and see if the failure persists; races hide as flakes.
• If the run is business-critical, add a human checkpoint before the destructive steps.

Prevention

• Checkpoint long runs so any failure resumes instead of restarting.
• Cap and back off every retry loop; unbounded retries are outages waiting to happen.
• Validate inputs at each pipeline stage; fail fast with clear errors.
• Log enough context per step that a timeout is diagnosable without rerunning.
• Give destructive steps a human checkpoint or a dry-run mode.

agent alt-text generator described decorative images instead of empty alt - how to fix it

TL;DR

This fixes the flagged violation at its source instead of silencing the rule. The agent wrote descriptive alt text for decorative images instead of leaving them empty, so screen readers announce noise. Follow the steps, re-run the scan, and gate the rule in CI so it stays fixed.

The error, verbatim

agent alt-text generator described decorative images instead of empty alt

Fix it step by step

Step 1

Mark decorative images with empty alt so assistive tech skips them.

Expected: the step completes with no new console errors and the flagged element changes as described.

Step 2

Teach the agent a decorative-vs-informative classifier: icons, dividers, and stock filler are decorative.

Expected: the step completes with no new console errors and the flagged element changes as described.

Step 3

For informative images, keep the agent's descriptive alt; only the decorative ones change.

Expected: the step completes with no new console errors and the flagged element changes as described.

Step 4

Re-run axe image-alt and spot-check with a screen reader.

Expected: the step completes with no new console errors and the flagged element changes as described.

When to use this skill

• Your scan report lists this exact rule or failure
• You are clearing automated accessibility failures before release or audit
• A CI accessibility gate is red because of this item

When NOT to use this skill

• Empty alt is the correct accessible choice for decoration, not a missing label.
• The issue only appears in manual screen-reader testing and no automated rule flags it
• You are doing a full manual WCAG audit; this skill covers one automated check

Compatibility

Agent workflow guardrail; verify with axe image-alt.

Variant phrasings

agent alt text on decorative images should be empty alt

Same underlying issue and the same fix. Searchers phrase it different ways; the remediation does not change.

Why it happens

The agent wrote descriptive alt text for decorative images instead of leaving them empty, so screen readers announce noise. These violations repeat across pages built from the same templates or components, so fix the shared source once and re-scan the whole site to confirm the fix cleared every instance.
