@Teodor

This is now added to the Api Action step via an inline extension update:

Expected and actual result

When an error is thrown by the api action, it's accessible in the $_ERROR variable

This variable is null

Replicate

1. Create an api action step

2. Add the url https://connect.mailerlite.com/api/subscribers

3. Tick the 'throw errors' box. See my settings:
   

   

4. Then in the catch put a response step where the text is going to be $_ERROR
   

   

5. It's populated as null
