Modbus data length error

Hi all,

I have an IO module that i am trying to get the data via Modbus TCP, i have already installed this node-red palette Modbus node

what i have done was, for the modbus server, and for Modbus Read, i have done a few configurations from the picture below, but when i tried to get data via tcp, it gave me this error, which states "data length error ", which i have no clue what it is.

Feel free to comment down below or guide me on this

Thank you very much!
