Based on the error message and research, this "403 - The caller does not have permission" error typically occurs when there are insufficient permissions set up for your Google Cloud service account. Here are the likely causes and solutions: 1. Missing Required Roles - Ensure your service account has AT MINIMUM these roles: -

Cloud Run Developer

(

roles/run.developer

) -

Service Account User

(

roles/iam.serviceAccountUser

) 2. Service Account Configuration - Verify that the service account credentials are properly configured in your Prefect work pool - Make sure the service account key (JSON) is valid and not expired - Confirm the service account exists in the same project where you're trying to deploy Cloud Run services 3. Project Configuration - Ensure the Cloud Run API is enabled in your Google Cloud project - Verify you're working in the correct GCP project Here's how to troubleshoot: 1. Check Service Account Permissions:

bash
   # List roles for your service account
   gcloud projects get-iam-policy YOUR_PROJECT_ID \
     --flatten="bindings[].members" \
     --format='table(bindings.role)' \
     --filter="bindings.members:SERVICE_ACCOUNT_EMAIL"

2. Verify Cloud Run API is Enabled: - Go to Google Cloud Console → APIs & Services → Enabled APIs - Search for "Cloud Run API" and ensure it's enabled 3. Review Work Pool Configuration: - Check that your work pool configuration includes the correct service account credentials - Verify the project ID matches where you have permissions To fix: 1. Add Required Roles (in Google Cloud Console): - Navigate to IAM & Admin → IAM - Find your service account - Click the edit (pencil) icon - Add the required roles mentioned above 2. Generate New Service Account Key (if needed): - Go to IAM & Admin → Service Accounts - Select your service account - Go to Keys tab - Create new key (JSON type) - Update your work pool configuration with the new key If you need help verifying your current work pool configuration, I can help you check the correct CLI commands for that.
