Zoho Creator Update a Task in Zoho Projects (DELUGE) Error 6890

Hello,

I'm trying to update a simple task on my Zoho Projects using Deluge on the app i've created on Zoho Creator.
This app haves a worklow that runs on record update.

This is my function on Zoho Creator Workflow:


And this is the error i get everytime:


I've tried to change the function, for exemple to only get the projects status or something else.
Everytime i get this error.

Thanks
