{"error":"Getting unknown property: craft\\commerce\\elements\\Variant::"}

Had Ship Station running fine.
I updated the feed to include the telephone number and getting this error;
{"error":"Getting unknown property: craft\\commerce\\elements\\Variant::"}
removed and rolled back the change but I am still getting this 500 error when the feed tries to run.

When I check thew logs I am seeing these errors:

Any ideas on how to resolve this?

I have found the problem! For anyone else how might come across this issue in Shipstation v2.1.0....

If the field for Product Images Field Handle is left as none then it the feed breaks.

I rolled back to v2.0.4 and it worked ok.
Checking the changelog.
2.0.4...2.1.0

So upgraded again and set the handle for the image and the export worked again.

I can see this was introduced in 2.1.0 - upon setting this field the export works again.
I have also posted this to a gihub issue - but heads up as you might nee do get this fixed ASAP, in case others hit problems.
