Hi,
I really appreciate this forum. It often helped me out by just reading posts and solutions.
Unfortunately not this time.
I try to parse a json from the output of an http request, but I get this error:
""
Here my input

The following schema I inserted from output of step HTTP request:

I can't see why the output of the http request ist Null... Or what to do if this error message is just misleading.
May anyone help me to fix this?
