Problem using Action for APIs - SAP Build Process Automation

[wvillam]

Hello,

I'm trying to use Actions on an Automation to execute an API that was Build From Scratch. The API itself works, but I couldn't use the result on any other step. There is an Error "The parameter 'value' refers to an object that doesn't exist. Please click the parameter to change it".

It doesn't work with a data type either.

The API has the output mapped: 

Is there any solution or anything I'm not taking into account?

Just in case someone has the same problem, I found that there is a Null variable within the mapped output. Removing or changing its type fixes the problem.
