I have some Serverless VPC Access in several gcp projects, and suddenly all of them is in bad condition and requires manual deletion. I also have a problem when i tried to delete the Serverless VPC Access with error message "An internal error occurred: Failed to delete a VPC Access Connector.". I've tried to delete and re assign the permission of gcp-sa-vpcaccess.iam.gserviceaccount.com and it work once to delete the Serverless VPC Access but now that method is not work anymore and I can't delete the Serverless VPC Access. Please help me, is there any other way to fix this? and is there any information related to this issue?
