Hi team, I've uploaded some CSV files, and have just created a join between 2 of the tables (these 2 tables are using 2 diff CSV files), and then one of the CSV file started giving this error, any clue why this is so?
Im pretty sure the data columns are there in the file itself..

oh I figured why(?) for some reason, I have an `activity_date` column that maps to this dataset (auto created by GD upon importing to LDM).

I removed that connection, and under `Data mapping`, fleshed out this column again, not as a mapping but as a column for this table.

I re-created the mapping btwn these 2 tables, and it works okay now :thinking_face:

Hi Alson, thank you for the update and for letting us know you resolved this issue :slightly_smiling_face:
