Referencing messages of other .proto files

I have seen there already similar problems published, I could not resolve the problem with the solutions proposed.

I am struggeling to reference a proto in another proto file.

I have the .proto file example.proto that is referencing A.proto in the dependency folder, example.proto is placed next to the dependency folder.

A.proto

syntax = "proto3";

package dependency;

message AttributeA {
  // Some attribute.
  string body = 1;
}

example.proto

syntax = "proto3";

import  "src/proto_test/dependency/A.proto";

package example;

message CheckRequest {
  // The request attributes.
  int32 id = 1;
  dependency.AttributeA att = 2;
}

The server file looks as following:

Server

const grpc = require("@grpc/grpc-js");
const PROTO_PATH = "./src/proto_test/example.proto";
var protoLoader = require("@grpc/proto-loader");

const options = {
  keepCase: true,
  longs: String,
  enums: String,
  defaults: true,
  oneofs: true,
  includeDirs: [path.join(__dirname,"/proto_test/dependency")]
};
var packageDefinition = protoLoader.loadSync(PROTO_PATH, options);
const proto = grpc.loadPackageDefinition(packageDefinition);

const server = new grpc.Server();

server.bindAsync(
  "127.0.0.1:50054",
  grpc.ServerCredentials.createInsecure(),
  (error, port) => {
    console.log("Server running at http://127.0.0.1:50054");
    server.start();
  }
);

Error

Error: no such Type or Enum 'dependency.AttributeA' in Type .example.CheckRequest#

Is there anything wrong with this code?

I do not know exactly why, but this code is working:

example.proto

syntax = "proto3";

import  "dependency/A.proto";

package example;

message CheckRequest {
  // The request attributes.
  int32 id = 1;
  dependency.AttributeA att = 2;
}

Server

    const grpc = require("@grpc/grpc-js");
const PROTO_PATH = "example.proto";
var protoLoader = require("@grpc/proto-loader");
var path = require('path')

const options = {
  keepCase: true,
  longs: String,
  enums: String,
  defaults: true,
  oneofs: true,
  includeDirs: [
    path.join(__dirname,"/proto_test/dependency"),
  path.join(__dirname,"/proto_test")]
};
var packageDefinition = protoLoader.loadSync(PROTO_PATH, options);

console.log(packageDefinition);

const proto = grpc.loadPackageDefinition(packageDefinition);

const server = new grpc.Server();

server.bindAsync(
  "127.0.0.1:50054",
  grpc.ServerCredentials.createInsecure(),
  (error, port) => {
    console.log("Server running at http://127.0.0.1:50054");
    server.start();
  }
);
