Steps to Reproduce

Create a simple webhook
Create an Event Rule with:

Object Types: extras.script
Event Types: Job completed
Action Type: Webhook
Action Object: Select the webhook from step 1
No conditions, no action data

Create a simple script:

from extras.scripts import Script  
  
class InfoLogger(Script):  
    class Meta:  
        name = "Infologger"  
        description = "Logs an info message to the log"  
      
    def run(self, data, commit):  
        self.log_info("Info log message")

Run the script from the NetBox UI
The Run Script Job Failed with error TypeError("'NoneType' object is not iterable")

Expected Behavior

The webhook should be sent successfully with the script job completed.

Observed Behavior

The Run Script Job Failed with error TypeError("'NoneType' object is not iterable")
And the worker logs the following:

14:52:51 default: handle(commit=True, data={}, job=<Job: Run Script>, request=<utilities.request.NetBoxFakeRequest object at 0x753dbbfa9550>) (8fc2a940-e170-41b3-a7e9-bae377ca26e8)
