Api show error, but link is updated at seatable base

Hello , I am trying to link rows in 2 table inside a base using the following api ( using n8n )

upon running the api, link is added ( as shown in black circle )

however, i receive an authorization error as shown below.

May i know what is the error about ( despite able to create the link between the 2 table ).

If the link can be added successfully, that means the API is working fine.
That you got an error, should be caused by a redundant request that you might have forgotten to remove from your nodes?

@Karlheinz thanks for the guide. yes, i forgot to remove redundant request… :smiling_face:
