Problem scancel'ing a job

Here's the traceback:

Same problem here. Using JupyterLab 2.2.6 and Node.js 10.19.

Well, the problem seems to be the ContentType conditional check:

if self.request.headers['Content-Type'] == 'application/json':
            jobID = json.loads(self.request.body)["jobID"]
        else:
            jobID = self.get_body_arguments('jobID')[0]

In my case the conditional takes the else path (not json) and then the cancel call fails with the "list index out of range error". But if If I remove the conditional and I just put:

jobID = json.loads(self.request.body)["jobID"]

Then it works. So it seems to be a confussion with the Content-Type here.

This was reworked as part of a migration to Lab 3, and the Content-Type was corrected.
