Removing any columns causes errors
Hi My source data is from a google sheet. It has not changed in any way - I have been working on it for the last month. However, suddenly I am getting errors. Today I re-imported the source ...
I think I figured it out - might be related to the credentials to access the data source.
I cleared my cache - went to "data source settings" and cleared all permissions - then recaptured them.
I was able to load this source again and make all changes necessary.
Anonymous - thank you for your assistance :)
Sometimes when I use Excel file as a source, I would get additional null columns. To prevent this, you can use Remove Other Columns to keep the columns you want instead of removing the columns you dont need.
