We have set up a pipeline with Pega infinity and deployment manager version 4.3 on tomcat and we use azure storage as a repository. The diagnostics of the pipeline is all green. When we trigger the CD pipeline we see that the artifact goes in azure storage and the development system sends a response to the orchestrator. The last few lines of the log from the PDM system are mentioned below. The pipeline just does not move to the next stage and there are no errors in the logs as well. It keeps on displaying the Ongoing image continuously, the work item has no assignment and is not waiting for anything, the process pzWaitForNextEnvironment is not a part of the pyWorkpage.pxStageHistory and it seems does not get executed. Any thoughts where it might be going wrong ?
