I am seeing the following error being repeated every 2 seconds in the uwsgi-error.log:

01:22:05 [Q] INFO Process-1:19112 processing [compute_thread_positions] 01:22:05 [Q] ERROR Failed [compute_thread_positions] - 'DiGraph' object has no attribute 'node' : Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/django_q/cluster.py", line 381, in worker res = f(*task['args'], **task['kwargs']) File "/usr/lib/python3.6/site-packages/hyperkitty/tasks.py", line 127, in _compute_thread_positions compute_thread_order_and_depth(thread) File "/usr/lib/python3.6/site-packages/hyperkitty/lib/analysis.py", line 55, in compute_thread_order_and_depth walk_successors(thread.starting_email.id) File "/usr/lib/python3.6/site-packages/hyperkitty/lib/analysis.py", line 37, in walk_successors obj = graph.node[msgid]["obj"] AttributeError: 'DiGraph' object has no attribute 'node'

I am running the docker version of Mailman, version 1.3.0. Any suggestions?

Thanks, Brian
