I guess @anon79585656 was asking for the response of the GET request on /forest/djangoSession call, not the /forest/djangoSession/count one.
The issue looks pretty similar to this thread, and we just need to make sure that the GET /forest/djangoSession actually return data or if the issue is located elsewhere (It looks like it does though, since I can see a 304 for this call on your last screenshot - But seeing the actual content of the request might help to investigate what is happing here)
Thanks in advance
