I can't replicate this on terraform 0.13.1 w/ AWS v3.8.0. Does it work for you on an earlier 0.13 version?

[DylanSp]

Just tried with version 0.13.1, same error.

If you do aws --profile idxdev ec2 describe-vpcs from the directory, does it work correctly?

Hi @DylanSp. Thank you for including the debug output. It looks like you're running Terraform on Windows. Is your AWS credentials file located at %USERPROFILE%\.aws\credentials? (Linux and macOS would be $HOME/.aws/credentials) If your shared credentials file is elsewhere, you'll also need to specify shared_credentials_file.

Also double-check that the profile is configured correctly in the shared credentials file. If the profile is not found in the file, it will display the same error.

@gdavison Explicitly specifying shared_credentials_file did the trick, thanks! I'm running on Windows, but using Git Bash; my shell was resolving ~/.aws/credentials to the correct directory, but Terraform apparently wasn't finding them without explicitly specifying the path.
