'Cloud run invoking another Cloud run with "Allow internal traffic and traffic from Cloud Load Balancing" fails with error 403
I have built a Django backend and deployed it in cloud run. I have also built a react frontend that was also deployed in cloud run. Frontend calls Django backend. Everything works while backend Allow all traffic, when I change it to "Allow internal traffic and traffic from Cloud Load Balancing" I get 403 error. Both are using VPC connector. And also both are on un-authenticated cloud Run.

Focus on your architecture and where the code is running.
- Your backend run on Cloud Run
- Your front ent? it's served by Cloud Run, but executed on your browser.
That's why, your browser haven't a serverlessVPC connector or something like that and the request to the backend come from the internet, nothing from your Cloud Run frontend.
