Pipeline failing with no error description (web) and log message "Error occurred propagating authentication context"

[nathan-v]

AWS AMI using AWS IAM role for permissions. All functionality (Creating ASGs, ELBs, SGs, etc) is working correctly. I created and configured a pipeline. At the deployment step it appears to successfully read/pull the ASG config and then this line below shows in the logs. At that point the pipeline goes to a fatal state with no useful error message.

What does your clouddriver.yml configuration look like? Does your aws.account configuration have a 'discovery' URL property? I ran into this issue because I had not failed to configure discovery with my Eureka URL.

Closing due to lack of activity.

Feel free to reach out to the Spinnaker slack if there are continued issues.
