Same error here since today – exact same message:
LogValkyrie: Error: FlowStep_ResolveSessionCandidates(): Candidate module […] failed validation with error: [http_error_500:valkyrie-cook-api.prod.ucs.on.epicgames.com]
Tried:
- New map
- Validation fixes
- Restarting UEFN and PC
- Duplicating the project
→ Still broken
Please confirm if this is a backend issue. Would be great if someone from Epic could acknowledge this, seems a lot of people are running into it.
