Request context

• URL: https://app.devguard.org/@gitlab/projects/quality-tools/assets/gherkin-behave-vsc/refs/main/events
• Culprit route: GET /[organizationSlug]/projects/[projectSlug]/assets/[assetSlug]/refs/[assetVersionSlug]/events
• Same trace ID (0bc591ca360941e89e23895b713db968) as issue 3610 (fetchProject), issue 3680 (fetchContentTree), and issue 3832 (client-side surfacing) — this is the 4th separate GlitchTip capture from the single request where the billing sidecar returned 500 for every endpoint under org @gitlab (projects, assets, refs, artifacts, content-tree). One root cause (billing sidecar outage/error for this org) fanned out into 4 distinct error groups because each data-fetcher throws its own typed error.

GlitchTip

• Issue: https://error-tracking.devguard.org/devguard/issues/3631
• Event ID: 019fc558a7f47b15ae82600745c74da5
• First seen: 2026-08-03T01:59:09.500Z

Start with src/data-fetcher/fetchAsset.ts:26-36 and the events route shown in the stack trace, then compare the related fetchProject, fetchContentTree, and client-side surfacing issues. Reproduce the cited @gitlab request and determine whether the billing-sidecar 500 is handled by shared work or needs a change here. Done means the events page no longer fails for the affected response and its error behavior is verified.
