Hi Alex,

My apologies for the confusion here. When you had put down:

"Created a new folder and added one linked schema -> export went OK including the linked schema
Added a query based on the linked schema -> got the error."

I assumed that meant that you were not having a problem with exports, but rather imports.

But I did reproduce the issue successfully. It seems to be isolated to having custom queries on those linked schema tables.

I'll setup a bug on this problem, but it appears that if you want to do an export, you will have to make copies of those custom queries, delete them, export your folder, then put them back.

Regards,

Jon
