…bility issues
"Show me the accessibility issues from Automate build <link>" had no route:
the Accessibility API takes only its own build id and answers an Automate
build id with 404, and nothing mapped one to the other.
A session run through the BrowserStack SDK belongs to the SDK's build, whose
id is also the Accessibility build id, and the session's test-code record
(GET /ext/v1/sessions/{id}/testCode, already used for self-healing) names it
as build_uuid. So reportUrl now takes an Automate session link (one call) or
build link (one more call, for any of its sessions) and reads that build's
issues through the existing build export.
A session not run through the SDK, an SDK run without accessibility testing
(a build the Accessibility API does not know) and an unknown Automate build
each get their own message instead of a bare 404, and the Automated Tests
404 hint now points at passing the Automate link.

A rabbit checks the build link bright,
Then follows sessions into sight.
The SDK trail points to a build,
Accessibility results are filled.
I thump my paws: the tests took flight!

Review comments at @src/tools/accessiblity-utils/report-fetcher.ts:
- Line 223: Update the build-summary lookup in getReportLink so every
unsuccessful response is rejected via build.ok after preserving the existing
specific 404 error for builds without accessibility results; successful lookups
should continue returning the build reference.
- Around line 108-109: Update the sessionId extraction in the URL parsing logic
to accept any non-empty opaque segment after “/sessions/”, including values such
as “sess-aaa”, instead of restricting matches to 40-character hexadecimal IDs.
Keep the buildId matcher unchanged and preserve the existing path-boundary
behavior.

Accept opaque Automate session IDs.
The matcher accepts only 40-character hexadecimal session IDs. Repository session data uses URLs such as sessions/sess-aaa. The matcher rejects these URLs before reportUrl reaches the session test-code lookup.
Suggested fix
- sessionId: url.pathname.match(/\/sessions\/([0-9a-f]{40})(?:\/|$)/i)?.[1],
+ sessionId: url.pathname.match(/\/sessions\/([^/]+)(?:\/|$)/)?.[1],📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Reject unsuccessful Accessibility build lookups.
If the build lookup returns 401, 429, or 500, this check lets getReportLink proceed. The export request can then hide the lookup failure behind a different error. Reject every unsuccessful lookup, while keeping the specific 404 message for a build without accessibility results. The lookup is the build-summary API request. (browserstack.com)

"Show me the accessibility issues from Automate build <link>" had no route. The Accessibility API takes only its own build id and answers an Automate build id with 404 "Build not found", and nothing in the MCP mapped one to the other.
The mapping. A session run through the BrowserStack SDK belongs to the SDK's build, whose id is also the Accessibility build id. The session's test-code record names it as
build_uuid:GET {automation API}/ext/v1/sessions/{session_id}/testCode(public, basic auth; already used by the self-heal tools and in the TRA capability index asget_session_test_code)So
reportUrlnow also takes:…/builds/{build}/sessions/{session})build_uuid…/builds/{build})sessions.json?limit=1) →build_uuidThe resolved build then goes through #501's build export, so the count, duplicate folding, CSV link and paging are unchanged. A session link reads the whole build's issues; the tool description says so.
Failures say what happened instead of surfacing as a bare 404 from the export:
testCode404)The Automated Tests 404 hint (wrong kind of build id) now points at passing the Automate link as
reportUrl.Verification
Ran this branch's build against the real API:
reportUrlNew tests cover both link shapes and the three failure cases;
npm run build(lint, format, 1332 tests, tsc) passes.Not in this PR: reading only one session's test (rather than its whole build). The build's
testRunstree links a session to its Accessibility test case (retries[].uuid), but how retried tests map sessions to attempts is unverified.🤖 Generated with Claude Code
