We migrated from 7.6 to 7.8

We have a SAIL UI with upload document feature which works well in 7.6. When we migrated to 7.8, the Upload Document feature does not work. No errors in server.log or application-server.log files.
But we get a UI error i.e. ---> "The file could not be uploaded. Please try uploading it again."

The file size is very small. So size is not an issue. The file type is also not an issue.

Also, we tried converting the RULE into a SAIL INTERFACE but it still did not work.

When I checked the SAIL INTERFACE, we got the following error:-


Interface Definition: Expression evaluation error : Invalid variable(s) found: ri!assetDetail,ri!listOfDocuments,ri!uploadedDocument,ri!isReadOnly.

But when I check it in the Expression View, I see the local variables:-

local!uploadedDocument: ri!uploadedDocument

What could be wrong?
