I got this error when doing a pulumi up

error: failed to load checkpoint: blob (code=Unknown): MissingRegion: could not find region configuration
error: could not create stack: An IO error occurred during the current operation: blob (code=Unknown): MissingRegion: could not find region configuration

Any thought?

Are you using S3 backend? It sounds like you don’t have a region configured in your default ambient AWS credentials?

yep, should I set it directly in the pulumi conf?
