memory_backend.py update_manifest() is expecting all new_obj STIX objects to have a "modified" element. Not all STIX 2.0 objects do.

Thanks, @cricard . I feel like we ran into a similar issue lately, but I can't find it. I agree this needs to be fixed.

I asked a question on the TAXII slack channel on ideas on how to implement this. Of course, no one answered the original question.

Try the public list vs. non-public Slack Channels?

Because "versions" is an optional property, the fix will be just to not populate that property when the "modified" property is not present.

After discussion on slack, it was decided to include the "created" timestamp for the one and only version of a Marking-Definition manifest entry
