Unhandled Exception: ContextualVersionConflict with PyYAML

[mikey-]

I have recently submitted a PR on aws-cloudformation-resource-providers-rds, which is using codebuild to run CI/CD, which is currently failing. While I don't have access to the build logs, I have been provided with the excerpt below and asked to open an issue here.

[2021-04-29T00:37:09Z] DEBUG    - Unhandled exception

Any help you can provide would be greatly appreciated :) Thank you!
