ASM shows white blank page on blocked applications

Hello community, 

Facing a very boring problem on F5's ASM module. Every application I put on "Blocking" Enforcement mode, returns a white blank page on violation generated. Let me show an example: 

ASM event logs show that request has been blocked

But my browser shows a completely blank page

Problem seems to be documentaded here: https://my.f5.com/manage/s/article/K000137377. But solution did not worked for me.

Not a single error is shown on DevTools on the browser. Javascript is enabled. 

Note: Blurred requests come from my personal password manager.
