Description
Fixes the CORS configuration logic to correctly handle the
ALLOWED_ORIGINSenvironment variable when set to "true" or "*", while maintaining support for comma-separated lists.What was done
parseAllowedOriginshelper insrc/app.config.ts.trueifALLOWED_ORIGINSis"true"or"*".falseifALLOWED_ORIGINSis undefined.test/cors.e2e.spec.tswith comprehensive scenarios covering all these cases.Why
The previous implementation incorrectly parsed
"true"as["true"], which caused CORS to reject requests and return HTTP 400 in deployment environments (like Render) that use this convention for public access. The new approach correctly maps these strings to the booleantrueexpected by NestJS's CORS middleware.
