@Tawenxd can you share with me the name of your message in the proto file?

Maybe there is a message that Proxyman hasn't supported yet.

and what proto version are you using? 🤔

Same problem here.

My sample code

category.proto

package com.example;

syntax = "proto3";

enum Category {
  WORK = 0;
  HOME = 1;
  FAMILY = 2;
}

task.proto

package com.example;

syntax = "proto3";

import "category.proto";
import "google/protobuf/timestamp.proto";

message Task {
  string title = 1;
  Category category = 2;
  Timestamp date = 3;
  bool done = 4;
}

tasksresponse.proto

package com.example;

syntax = "proto3";

import "task.proto";

message TasksResponse {
  repeated Task tasks = 1;
}

@florentmorin I found there are multiple issues from your proto files:

When adding the task.proto, Proxyman prints this log (Sorry that Proxyman didn't display any error alert)

[ProtobufRawImporter] ⚠️ ERROR: File not found.
[ProtobufRawImporter] ⚠️ ERROR: File not found.
[ProtobufRawImporter] ⚠️ ERROR: Import "category.proto" was not found or had errors.
[ProtobufRawImporter] ⚠️ ERROR: Import "google/protobuf/timestamp.proto" was not found or had errors.
[ProtobufRawImporter] ⚠️ ERROR: "Category" is not defined.
[ProtobufRawImporter] ⚠️ ERROR: "Timestamp" is not defined.

Here is the correct version:

category.proto

syntax = "proto3";

package com.example;

enum Category {
  WORK = 0;
  HOME = 1;
  FAMILY = 2;
}

task.proto

syntax = "proto3";

package com.example;

import "category.proto";
import "google.common.proto";

message Task {
  string title = 1;
  Category category = 2;
  google.protobuf.Timestamp date = 3;
  bool done = 4;
}

taskresponse.proto

syntax = "proto3";

package com.example;

import "task.proto";

message TasksResponse {
  repeated Task tasks = 1;
}

The difference from your original proto files:

The syntax = "proto3"; must be located on the top of the file
Use google.protobuf.Timestamp instead of Timestamp
Use import "google.common.proto";
Must import the category.proto -> task.proto -> taskresponse.proto (It's a bug from Proxyman)

Then Proxyman can capture and parse it properly.

Conclusion

I agree that it's a huge challenge issue from Proxyman 😿

I suppose that I should display the error and instruct the user to generate a proper proto file.

To fix it, I will write an auto-correction when you guys import the protobuf file. It will automatically fix it 👍

it's not your fault @florentmorin. Just wondering: Are your proto files automatically generated? If yes, which tool is it? 🤔

Hey @florentmorin @basic1aw and @Tawenxd, if you don't mind, please try this Beta build: https://proxyman.s3.us-east-2.amazonaws.com/beta/Proxyman_2.35.0_Fix_protobuf_issue.dmg

Proxyman now can automatically fix the issue on your imported Proto file 👍

However, you have to import in the correct order of dependency (Take a look at this example: https://github.com/ProxymanApp/Proxyman/issues/849#issuecomment-971176920)

Additionally, it will display the error when importing the file.

@NghiaTranUIT Sorry, but I have a problem with timestamp import.

With this syntax, it works with Node / Swift, but don't work with Proxyman:

import "google/protobuf/timestamp.proto";

While it's the opposite with:

import "google.common.proto";
