Preview broken

[valentin78]

update version from 1.4.0 to 1.7.1 and looks like you lost ability to preview (PDF). It was working in 1.4.0 :

Also if I try to save response (application/pdf) to file, I'm getting error message

Hi @valentin78

This has been fixed in #1490 and I will release a patch fix for this shortly.
