@scarytom could you please also provide the following information? (whatever you can):

• Authentication method (i.e credentials file? config file? env variables? profile? something else?)
• Output of cdk diff with -vvv? (account numbers redacted).

Thanks!

[scarytom]

Authentication is via AWS environment variables

The output above is already from cdk diff -vvv. I'm not sure the full output adds much, but I can attach that tomorrow if that helps at all.

Confirm that, I have the same issue.
