Hi @stephenmsachs, thank you for reaching out. I have replicated the scenario with CodeBuild and having AWS CLI version aws-cli/1.18.147 and with "file://" without the b and it worked. I was able to import key pair and describe it too. For further look, could you please provide full debug logs and also any other relevant steps you may have done.

In regards to with “b” on "fileb://", it would be for using CLI V2 or you can revert to the v1 behavior with the configuration: cli_binary_format=raw-in-base64-out (#4969 (comment)). This "fileb://" can be seen also from the current documentation: https://awscli.amazonaws.com/v2/documentation/api/latest/reference/ec2/import-key-pair.html#examples. Please let me know if you have any other questions. Thank you.
