Hello @js37 thanks for reaching out. I tried to replicate the issue using the same AWS CLI version (2.27.43) and Homebrew installation on macOS, but did not get the error. Was your environment modified and could you please clarify if your environment's filters.py is the same as our repo: https://github.com/aws/aws-cli/blob/v2/awscli/autocomplete/filters.py ? Thanks.

The filters file is the same.

It must be something with one of my AWS accounts. I am able to recreate the problem in CloudShell, but can't recreate in a different account.
