Error on Node Red

Hi. I am simulating data on Node Red and trying to publish the data on Favoriot platform. I am following this tutorial ( https://platform.favoriot.com/tutorial/v2/#node-red-with-raspberry-pi-using-http ) from step 12 to 16 (Previous step is skipped since I am generating random data using Node red random node). However, the function node put an error on the access token (I am using the Read/Write apikey from account setting). Can anyone help me in knowing what may cause it?

PS: I try to attach picture but I cannot find the attach pic button.
