Hi @ajnovice, thanks for the submission. The problem you are experiencing is due to a marking being placed on this CIQ Instance Object, but is not added to the final STIX_Package at serialization. Thus, the stixmarx tool is unable to find it and fails hard. This is a problem on the stix2slider not on stixmarx.

I noticed you opened the same issue on that project. I will close this one since is a duplicate of oasis-open/cti-stix-slider#24.
