Pipeline hangs after triggering codebuild step. The codebuild project finishes properly but the pipeline keeps waiting there forever. 

It hangs after providing the URL for codebuild and does not show the cloudwatch log url. 

The pipeline was working till Sep 29 5pm EDT .. after which i might have done an upgrade of all plugins which would have upgraded codebuild to 0.53 and caused this issue. Downgrade to 0.52 did not solve the problem. 

Tested with new jenkins deployment and codebuild 0.54 version - same issue. 

All our pipelines are impacted due to this - planning on recovering from backup if this does not resolve
