Describe the bug

I've encountered an unexpected behavior with error handling in the syncEnvVars callback:

Current behavior:
We throw an error when required env vars are missing
The error appears as a warning message
Deployment continues despite the error

Expected behavior:
Deployment should stop when the error is thrown

To reproduce

Just throwing any kind of error in the syncEnvVars callback
