Get Notebook Exit Value from Fabric REST API

[Creykish]

There is currently no way to get the exit value defined by notebookutils.notebook.exit("Exit Value") from a Notebook via the Job Scheduler api. 

Currently, the only way to get something approximating this is to raise a value and have the notebook error like:

raise(Exception("<Exit Value>"))

and then parsing it from the response as:

{

    'id': '<id>',

    'itemId': '<itemId>',

    'jobType': 'RunNotebook',

    'invokeType': 'Manual',

    'status': 'Failed',

    'failureReason': {

         'requestId': '<requestId>',

         'errorCode': 'Exception',

         'message': '{"name":"Exception","value":"<Exit Value>","traceback": "..."',

    },

    'rootActivityId': '3f0a6ff0-3e64-4978-a0c7-fee862e3c5fd',

    'startTimeUtc': '2026-01-08T22:28:52.3082611',

     'endTimeUtc': None

}

But this is a really stupid way of doing it.
