Attempted to add a column value to an existing item but it doesn’t work.
Tried JSON.stringify it and it still doesn’t work.
I want to make a WhatsApp bot that sends a message to Monday update section and if the client’s number doesn’t exist I want to make a new item with the client’s name(no problem with that) but when I add the phone number at first it told that it supposed to be in JSON type and after that, I’ve changed it to JSON and it said that it can’t change column value of ‘undefined’.
what does it mean?
Thx for the help.
