CDK Bootstrap requires --app

See original GitHub issue

❓ General Issue

The Question

I recently updated my project aws-cdk dependencies from v1.35.0 to v1.38.0 and I seem to be experiencing a new issue where if I call npx cdk bootstrap aws://${TARGET_ACCOUNT}/${AWS_REGION} in my bash script, I get the error --app is required either in command-line, in cdk.json or in ~/.cdk.json previously I was able to use this command without --app.

I noticed that there was something changed in this area in v1.36.0, see #7510.

I’m struggling to find any supporting documentation on this change where --app is required to run cdk bootstrap.

Is this intended functionality, or has a bug been introduced?

Below is from my CI/CD pipeline logs. I want to add that I don’t bootstrap from an existing product. This is a CI/CD pipeline job to bootstrap a new account.
