I have been using Direct VPC egress in google cloud run since May 2, 2024 to access to Cloud SQL via private IP in the same network. I have 2 environnments prod and staging, same configurations except min-instances (1 in prod and 0 in staging)
Since June 18 I have been receiving these errors (only in staging) when the number of instances remains 0 for more than 20 minutes. (Only for the first request, in other cases works well)
Instance failed to start because permission was denied when creating an address in the subnetwork, Please check IAM settings.
Even though I assigned the networkUser role to the cloud run service agent.
