When the backend server creates a redirect request to process a callback on the frontend app, cloud run response includes "access-control-allow-origin: \*" from " server: Google Frontend"   Chrome network trace shows the result was "CORS error" wildcard origin not allowed. The request for redirect header " origin: null" was included by Chrome.  How do we configure cloud run not to include access-contron-allpow-origin: \* or send a custom origin matching the app custom domain hosted on cloud run?   **Best answer by guillaume blaquiere** Hi Mali. Cloud Run doesn’t include the allow origin header by itself. You app must do it. Review your code, your libraries, your configuration, you should have an existing layer that perform that operation.   --- ## Recent Articles [Data Analytics](https://www.c2cglobal.com/articles/tag/data-analytics) ## [Generative AI: Are You Behind?!](https://www.c2cglobal.com/articles/generative-ai-are-you-behind) Review the latest insights from the AI Readiness Report.
