@NghiaTranUIT commented on GitHub (Oct 21, 2022):

Thanks @pepas-everly, please send me the ProxymanLog/HAR file which contains the JSON.

To workaround, you can:

Click on the + button on the Request/Response panel
Select JSON
At this point, there is a JSON Tab on the Request/Response panel -> It will always beautify the JSON if it's possible.
