GET /api/external-tools/{id}/config is returning null
Analyzing telemetry and recent deploys…

Found 2 likely root causes. Pick one to investigate:

  • Schema Drift high confidence

    JiraToolConfig was updated without a migration — GET returns schema 2.1 but callers expect 1.4, causing silent null failures on auth_method.

  • Stale Credential Cache medium confidence

    The external_tool_auth TTL dropped from 3600s to 300s in v2.3.1, so tokens may expire mid-request and produce the intermittent 401s on /api/external-tools/{id}/config.
