Unrecognized reference format error

[mmundy42]

I'm trying to update a Model to use the genome that is stored in the workspace and I'm getting this error trying to get the model after the update:

JSONRPC error data:Unrecognized reference format:/reviewer/home/models/.PrivateGenomeModel/563178.138.genome at /data2/microbiome/software/patric/dev-20150521/deployment/lib/Bio/KBase/ObjectAPI/utilities.pm line 179.

Why is that an unrecognized reference format?
