HTTP output is missing data

Here is my scenario:

sceenario.json (10.3 KB)

I need to use my API key to log in to a service from which I will receive a SID. I need the SID to log in to service number 2.

The blueprint shows a module attempting to log in to service number 1. The module works correctly and shows code 200 upon execution.

However, the problem is that the output of this module is truncated, meaning it is shorter than it should be. Unfortunately, this truncated part contains my SID.

I want the HTTP module to give me the same output as ReadyAPI does.
The input of ReadyAPI and HTTP module is the same.

Output from ReadyAPI:
