assemblyline_submit: KeyError: 'submission'

I am trying to set up the assemblyline_submit module as packaged with the misp-docker deployment.

After configuration, when I attempt to a URL for enrichment, I receive the error: "Something went wrong, look in the server logs for details"

Looking at the logs of the misp-modules container, I see:

KeyError: 'submission'

Running the same command manually using the latest version of the assemblyline_client (https://cybercentrecanada.github.io/assemblyline4_docs/integration/python/#submit), there is no "submission" key. "sid" is a key of the submission result itself, so line 73 should just be sid = submission['sid'], I think.

Start in misp_modules/modules/expansion/assemblyline_submit.py at the handler line shown in the traceback, and compare its submission response handling with the Assemblyline client documentation linked in the issue. Reproduce the URL enrichment request and confirm that the returned sid is handled without a KeyError.
