Internal Server Error trying to retrieve search results from custom module

[achung12]

When my module tries to retrieve results from a search launched by a user, it produces this error:

GET http://localhost:8000/en-US/module/system/Splunk.Module.[module_name]/render?sid=[job_id]&client_app... 500 (Internal Server Error)

I believe it's being caused by a line in the python script in generateResults():

job = splunk.search.getJob(sid, sessionKey=cherrypy.session['sessionKey'])

I'm running Splunk 4.2.2

Any help is appreciated

EDIT:
This is the entire error:

EDIT2: I've tried a few other things...

result = os.popen('curl -u admin:changeme -k https://localhost:8089/services/search/jobs/'+jobId+'/results/').read()

returns an empty string when used in the module; the equivalent works in a shell

return httplib2.Http().request('https://localhost:8089/services/search/jobs'+jobId+'/results/', 'POST', headers={'Authorization': 'Splunk %s' % sKey})

gives me the above error when used in the module; works in the python interpreter

key = splunk.auth.getSessionKey('admin', 'changeme')

my_job = splunk.search.dispatch('search [terms]', namespace='search')

also gives me the above error when used in the module; works in the python interpreter

[achung12 · Accepted solution]

Figured it out.. dumb Python mistake. Needed to cast my return variable to a string first, as it expects a string. Didn't realize the error message was referring to that.

[achung12]

I get the same error when I do this, after authorizing and given "sKey" and launching a search with the id "jobId":

httplib2.Http().request('https://localhost:8089/services/search/jobs'+jobId+'/results/', 'POST', headers={'Authorization': 'Splunk %s' % sKey})

[achung12]

I'm also subclassing from the DispatchModule, if that helps

The whole traceback is too big to fit here, but it starts with:
File "/Applications/splunk/lib/python2.6/site-packages/cherrypy/_cprequest.py", line 606, in respond
cherrypy.response.body = self.handler()

and ends with:
File "/Applications/splunk/lib/python2.6/site-packages/splunk/appserver/mrsparkle/lib/util.py", line 577, in apply_etag
hash.update(contentstring)
TypeError: update() argument 1 must be string or read-only buffer, not int

At the moment, I'm just trying to retrieve search results

I need more information, such as the specific error in web_service.log and more information on what the module is trying to do.
