Script Runner Error on post function: com.atlassian.jira.exception.CreateException: An unknown exception occured executing Validator

[Robert Stoffers]

When attempting to execute a post function using the Script Runner plugin to create a sub-task (e.g. upon reopening an issue) the function fails to execute. The following error is observed in the catalina.out log when this occurs. . . Has anyone seen this before and know how to resolve it?

Another update:

After going through the log and script, it looks like failing at User Level Validation/Permissions. When getting the user parameters Jira is returning a null value rather then the intended information and this only happens for some users and not others.

Code:
def user = WorkflowUtils.getUser(params)
WorkflowUtils.actionIssue(null, sub, subtaskAction as Integer, user, [:])

Error:
Caused by: java.lang.NullPointerException
at com.atlassian.jira.workflow.validator.AbstractPermissionValidator.hasUserPermission(AbstractPermissionValidator.java:50)
at com.atlassian.jira.workflow.validator.PermissionValidator.validate(PermissionValidator.java:50)
at com.opensymphony.workflow.AbstractWorkflow.verifyInputs(AbstractWorkflow.java:1512)
... 215 more

I'm not sure however why Jira would be passing a null value sometimes to the variable.

This is using the out of box Create a sub task script. I've copied it below from our instance if it helps? Unfortunately there is a 2000 char limit on posting it here.

[RambanamP]

can you share your code ?

[Timothy]

Well, the error is telling you what's wrong. You passed a null value. Check all your inputs.

[Robert Stoffers]

The steps to reproduce are to edit a workflow and create a post-function function for the transition using the out of box Create a sub-task script.

The inputs were as follows:

Condition: left blank (should eval to true according to instructions)

Target Issue Type: Sub-task (is valid for the project)

Additional issue actions: left blank

Subtask Action: left blank (optional according to instructions)
