Proxyman appears to be messing with body even if no modification is made

[triwav]

Description

I am having an issue that a request I am trying to modify the url of with the scripting tool is modifying the body in some way. My best guess is that because the code is trying to convert the body to be compatible with the Javascript code it is causing the issue. I do know a request I send in Proxyman has a Content-Length: 3590 and the same endpoint hit with Charles is much smaller at Content-Length: 2207 which would support the theory that there is some conversion going on that isn't quite right. Is there some way to tell it to just use the original body not the modified version? I'm happy to share Charles and Proxyman session files privately

Steps to Reproduce

1. Setup the scripting tool in Proxyman that matches the url
2. Make request
3. Request fails in Proxyman but succeeds in Charles

Current Behavior

Seems to mess with the passed in body

Expected Behavior

Should not mess with passed in body

Environment

• App version: Proxyman 5.7.0
• macOS version: 14.4.1
