Original GitHub issue: https://github.com/ProxymanApp/Proxyman/issues/826

Originally assigned to: @NghiaTranUIT on GitHub.

Proxyman version? (Ex. Proxyman 1.4.3)

2.20.0

macOS Version? (Ex. mac 10.14)

10.15.7 (19H15)

Steps to reproduce

Problem Description:
I set up some remote mapping rule, then I found out proxyman fails to process the remote mapping on requests when they include the angle brackets in the parameter.

Steps to reproduce:
For example, I setup the a mapping rule for directing google traffic to amazon (you can checkout the rule from the screenshot below)

When I entered "https://www.google.com/" in my browser, proxyman just redirects me to the amazon, and this is what I expected.
But when I entered "https://www.google.com/?test=[123]", which includes angle brackets in the request parameter, then proxyman fails to process the request and I just get a request from google back instead of amazon. Could someone please take a look at this issue?

By the way, I wonder if there are some errors happen during the request processing in postman, is there any place that I can see the log to debug? At first I thought this issue happened because I didn't setup the remote mapping correctly, and it issue took me quite a while to figure out...

Expected behavior

Screenshots (optional)

Hey @tylerw8bits look like it’s a bug when parsing the [] in the query. I will fix it 👍

To work around, can you try Map remote with the Scripting tool? It’s super easy to setup

I have no problem of parsing request with angle brackets in the parameter via scripting on my end. Thanks for suggesting that!
But I still wonder if Proxyman has a debug tools for me to see the logging from the map remote
