I'm getting this error when running

pulumi import

. How can I troubleshoot this?

Try upgrading the version of pulumi/pulumi you are using. If that doesn’t work, please open a bug report in pulumi/pulumi.

This has just been fixed in https://github.com/pulumi/pulumi/pull/15197/files, which will be in the next release. We're planning on creating a new release today. If you want the fix quicker than that, you can use a dev release (using

curl -sSL <https://get.pulumi.com> | sh -s -- --version dev

)
