Hi Anubhav Agrawal,

I see that you are getting a stacktrace when a workflow action is happening.  From reviewing this I can see that you're using a postgresql database.  And that column "source_node_id" in the nodeassociation table is unable to store a null value because there is a constraint in that table of the SQL database against storing such null values for that field.

That said, it's not clear to me yet what is causing this. I have not found any other reports of this specific error that clearly indicate a cause.

1. What version of Jira is this? 
2. Is this by chance a Jira Data Center deployment?  

I suspect that you have a postfunction in the workflow that is trying to save some value, but it is unable to do so in the current setup/configuration.

Perhaps you have some plugin to Jira that is providing some additional post function actions here?  If we could establish which plugin that is here, perhaps we could better direct you in regards to which plugin vendor to seek support from in regards to this issue.

Please let me know the results.

Andy
