Import Script Error: Script failed with error: Script output property '{Project with id=17 key=EMB Applications}.key' should be of type string

I am currently working on importing from FogBugz, and I have it to the point where it is getting the issues and the updated issues. But after it runs those two parts, I get the following error below. I have tried to trace it down, but I cannot find where this is occurring. I am still trying to find code that tells me who the client functions are run and in which order, which I think would help, but unsure what to do here to resolve this issue. Any help would be useful.
