As whatever steps I have written in that activity are not executed and after the deadline for the wait shape expires the case is resumed to the next stage(without even executing the activity configured for standard queue processor)
It’s supported in 23. I believe you’re not passing the required parameters on pyQueuePage for Obj-Browse. Please trace the activity (attached screenshot).
Troubleshooting steps:
Ensure the Standard QP is running from Admin Studio.
Execute the activity as standalone by passing the required parameters and it works as expected. It will be easier to fix the bugs by running as standalone activity
Trace the Standard QP to identify the pyQueuePage has the required parameters for the Activity rule.
