Unable to move a list in a board using Trello API

I tried to move a list inside a board using trello API, I received status code: 200 from the server but the list did not move inside the board.

sample url = “https://trello.com/1/lists/{{listid}}?pos=99999&key={{key}}&token={{token}}&invitationTokens=”

Can you provide a bit more context?

What was the content of the response? Did the position of the list update to 99999? What are the positions of the other lists on the board?

A position of 99999 may not have been sufficiently large enough to be the last list.
