if simplejson is installed (no dependency graph is displayed within the gui). Removing simplejson resolves the issue. Versions used here are Flask 1.1.2, gunicorn 19.9.0, fireworks 1.9.5. This is not a Fireworks issue, but rather some issue between Flask and simplejson also pointed out elsewhere. Just wanted to point that out here again, in case anyone would search for this issue.
