fix: return 404 instead of 500 for UUID work-item lookup in v1 API - #9898
Conversation
Requests to /workspaces/{slug}/issues/{project_identifier}-{issue_identifier}/
also match a bare UUID (split at its last dash), which then hit
sequence_id=<hex> and raised ValueError instead of a clean 404. Reject
non-numeric identifiers up front and return 404, with contract tests
covering both the UUID and normal identifier paths.

What changed in this PR
Fixes UUID-shaped work-item lookups returning 500 by returning 404 for invalid identifiers while preserving valid lookups.
Changes:
- Adds identifier validation before database queries.
- Adds contract tests for UUID and valid
PROJECT-sequencepaths. - Remaining issue:
isdigit()accepts Unicode digits that may still cause conversion errors.

non-decimal Unicode digits before the sequence_id lookup, preventing invalid

- str.isdigit() is True for characters like "²" that int() cannot parse, so those identifiers still reached sequence_id and raised ValueError (HTTP 500). isdecimal() only accepts characters int() can parse. - Replace the bare-UUID test with a non-numeric identifier test, and add a test for the "²" case. - Coerce response.data["id"] to str in the 200-path assertion.

Description
GET /api/v1/workspaces/{slug}/issues/{project_identifier}-{issue_identifier}/also matches a bare work item UUID, because the route splits at the last dash.
