Error while importing protos with illegal name '}'

[tran302]

We are using proto message with custom validation rules implemented based on https://github.com/envoyproxy/protoc-gen-validate

Below is sample mssage:

syntax = "proto3";
package demo;

service DemoService {
    rpc Demo (DemoRequest) returns (DemoResponse) {}
}
message DemoRequest {
    string number = 1 [(validator.rules).decimal = { }];
}
message DemoResponse {
    string response = 1;
}

Above proto fails to import with error illegal name '}' because there is no specific validation rule defined for (validator.rules).decimal. If I change this to [(validator.rules).decimal = { precision: 1 }], it imports fine.
Could you please support this format?

Unfortunately that is a limitation of protobuf.js the issue is tracked from here:
protobufjs/protobuf.js#1256

We are thinking to use a forked version of protobuf.js until this is merged in

It looks like that protobufjs/protobuf.js#1256 is already merged long time ago, should we update the protobufjs dependency from 6.8.8 to the latest one 6.11.2 ? I'm happy to create PR for this
