Hi! I saw that there are some old posts on this topic but it looks like recently Monday.com changed so that text can be accepted into the phone column: https://support.monday.com/hc/en-us/articles/360014205860-Zapier-JSON-Formatting-Examples.
I am getting this error message when I try not mapping phone, when I try phone as raw text, and when I try phone with the instructions given on this post.
Is there maybe a bug happening?
