[Incident][108dev] Questions API 500 due to Cosmos env drift (empty endpoint/database)

[Cataldir]

Summary

Questions frontend is failing with internal server errors on:

• GET /api/questions/questions
• GET /api/questions/assemblies

Observed error

API payload returns:

• Invalid URL scheme or hostname: SplitResult(scheme='', netloc='', path='', query='', fragment='')

Root cause

COSMOS_ENDPOINT and COSMOS_DATABASE were empty in tutor-questions-108dev runtime environment.

Immediate remediation plan (live)

• Re-apply Cosmos env baseline to 108dev container apps.
• Re-validate Questions endpoints through APIM.
• Log actions and evidence in [Incident][108dev] APIM/SWA integration regressions: CORS + configuration themes 500 #139.

Live remediation applied and verified.

Root cause confirmed:

• tutor-questions-108dev had empty runtime env values:
  • COSMOS_ENDPOINT=""
  • COSMOS_DATABASE=""
• This produced 500 on:
  • GET /api/questions/questions
  • GET /api/questions/assemblies
  • Error payload: Invalid URL scheme or hostname: SplitResult(...)

Break-glass correction executed (108dev):

• Re-applied Cosmos baseline env vars across container apps, including tutor-questions-108dev.

Verification:

• GET /api/questions/questions -> 200
• GET /api/questions/assemblies -> 200

Follow-up note:

• Assemblies payload now includes essay assemblies as well (cross-domain data contamination in shared container); this is tracked separately.
