Original GitHub issue: https://github.com/ProxymanApp/Proxyman/issues/1261

Originally assigned to: @NghiaTranUIT on GitHub.

Proxyman version? (Ex. Proxyman 1.4.3)

Proxyman Version 3.6.0 (30600)

macOS Version? (Ex. mac 10.14)

macOS Monterey 12.3.1 (21E258)
macOS Monterey 12.4 (21F79)

Steps to reproduce

Turn on scripting (in my case it's a simple if-else what colors the request/responses)
Get your request with the original integer value (in my case it's a "randomTimestamp")

Original value: 1655989280365

I can see this value in the following requests like this:

Without the scripting: 1655989280365
With the scripting: 1655991846719.0002

Expected behavior

The original value should be kept until the script modifies it (or the tester manually overwrites it).

Look like it's a different issue, when passing this big int to JavascriptCore, it might be converted improperly.

I will check it out 👍

@torokdnl please try this beta build: https://proxyman.s3.us-east-2.amazonaws.com/beta/Proxyman_3.6.0_Fix_scripting_with_big_number.dmg

I redesign the algorithm to make sure it maintains request/response JSON. It works will for big number or float/double too 👍

If you're curious what causes the bug behind the scenes. It's because the JSONSerialization.data(withJSONObject::) poorly convert these NSNumber to String. Thus:

2.02 -> 0.0199999
1655989280365 -> 1655991846719.0002

@NghiaTranUIT -

The build is working correctly, integers remain integers. Thanks a lot for fixing it quickly and for the explanation as well!
