ADO <-> Make.com -> Monday.com - [403] User unauthorized to perform action [ Error Code: UserUnauthroizedException / Error Details: {} ]

Hello,
I had a problem. I found the solution. I wanted to note it here, as I havent seen it mentioned anywhere else.

Setup
Make.com queries Microsoft ADO via a tag and then updates a board in Monday.com with all instances of that tag.

This works well. We query tag ‘ABC’ and get back the 10 tickets that were tagged with ‘ABC’.
Today I tried to query ‘ABC+1’ and got the following error message in Make.com against Monday.com
[403] User unauthorized to perform action [ Error Code: UserUnauthroizedException / Error Details: {} ]

However, it had nothing to do with authorisation. Something along with way didn’t handle the ‘+’ in the tag query.
If you get the same problem, go to you Data Store in Make.com and remove any pluses.

Case closed.
