Recommended join throws Unexpected error occurred


#1

Not sure if Recommended joins is a new feature in 3.1 but it throws an Unexpected error when it opens. Reason for error is the suggested join is between an integer column and string column. I can switch to custom join and create join so no issues. Would like to see a better error message rather than “Unexpected error” and\or a to link more details (ie Job). Preference is for recommended joins to not recommend invalid joins.

fyi- underlying error in job states “UnsupportedOperationException: Join only supports implicit casts between 1. Numeric data”
