Hello, I'm currently building a rather big script using the API and I'm now running into a problem that I can't understand. I'm just trying to add rows under another one, so I specify the parentId (which I've been doing for a really long time and it has always worked until now).
status: 400 Bad Request
"message": "Invalid parentId: 2621140536977284",
^ Here's one of the error I get, it always happen for the same row in my script. When I wipe the sheet and start again, it will throw the same error with newly created parent Id (created just before I try adding new rows under)
I'm sure this Id exists in the sheet. I can print it and it has always been there. After all that's logical since I get the Id from a preceding result of an add_rows method call. Does someone have any idea how this can actually be possible ?
