Create Task activity in workflow is not creating task

[Nithin21]

 I want Change task to be auto-assigned to assignment group selected in Change Request

I have added User approval to "Change Request - Normal" workflow

Once approved, there is a Branch task that leads to 2 "Create Task" activities. 

>> Wait for Completion is set to True

When I approve the change request ->Both the "Create Task" activities are in "Running" state

Expected result:
2 change tasks created for this change request

Assignment group is set as that of change request

Actual result:

Change task is not created . 

Script mentioned in both "Create Task" activity

1. I have the same issue, I did check the task type, but I'm still not getting a newly created problem task
2. Is an advanced script necessary?

[Mike Patel]

No, advance script is not necessary. Does your workflow gets kicked off. Check workflow context.

Thanks Mike, I was able to get the workflow working. I followed the steps of Automating Problem Management Workflow, hopefully, others will find it helpful as well

Will the workflow works and the guide helped tremendously, I am not getting the unexpected error where the tasks are not being moved to the viable state and I am getting the error message Error Message: Invalid state transition. Can not update from state '(-5)' to state '(1)' with given values.

I am currently troubleshooting this and believe it has something to do with the default business rule on the task table, but I am not sure as of yet.
