Original GitHub issue: https://github.com/ProxymanApp/Proxyman/issues/1479

Originally assigned to: @NghiaTranUIT on GitHub.

Description

I'm not sure, if it's only for me or not, but in my case, every boolean field of protobuf message appears as number.
So if the value is true, it shows as 1 (in JSON form of protobuf parsed value), and if the value is false, it is not shown entirely (because it is default value which doesn't include an actual value in packet?)

Steps to Reproduce

Set Any protobuf message that has a boolean field in Protobuf Rules.
Check that field value in protobuf parsed view in request or response tab.

Current Behavior

Boolean field value appears as number. (1 or nothing)

Expected Behavior

Boolean field value appears as boolean. (true or nothing)

Environment

App version: Proxyman 3.15.0
macOS version: macOS Ventura 13.1

Just wondering: What is the field type (described in protoc/desc file)? Is it Int or Boolean?

@NghiaTranUIT

I'm not familiar with proto.desc file format, so I'm not sure if I check correctly. But when I check, I find it is 'bool'. (the value of field.type is 8)

I refer to code of following link.

to read desc file.

to find which type has value 8.

@NghiaTranUIT any word on this bug fix or a possible workaround? I am seeing the same issue on Proxyman Version 5.10.0 (51000) | macOS: Version 14.5 (Build 23F79) when inspecting protobuf responses. In particular, this is quite limiting when trying to use the map local tool as all bools are being converted to integers.

For me bools are shown as:

"blockingInterstitials": {
    "bool_1": 0,
    "bool_2": 0
},

when they should be shown as:

"blockingInterstitials": {
    "bool_1": false,
    "bool_2": false
},
