I am trying to run a job in my cluster with a private ECR image in my container runner.  
I get an error while running the job saying I am not authenticated with AWS: CircleCI failed to run this build, check your config. Try re-running the build and if this issue persists, open a **[Support ticket](https://support.circleci.com/hc/en-us)**. **Detail: could not make new task: error authenticating with ecr: aws credentials not found**
