Error when migrate to connect_grpc_bridge (google.protobuf.message.DecodeError)

Hello, I am trying to migrate my project on buf connect and I have the following error in my browser console.

My grpc framework is based on django and https://github.com/socotecio/django-socio-grpc My envoy layer is up to 1.26

Below my front use case:

import { createPromiseClient } from "@connectrpc/connect";
import { createConnectTransport } from "@connectrpc/connect-web";

import { UserController } from './proto/js/sample_back/user_connect'
import { UserListRequest } from './proto/js/sample_back/user_pb'

// This transport is going to be used throughout the app
const transport = createConnectTransport({
  baseUrl: "http://localhost:20251",
});

async function user_list_test(auth) {
  const request = new UserListRequest();
  const headers = new Headers();
  const promiseClient = createPromiseClient(UserController, transport);

  headers.set("Headers", JSON.stringify(
    {
      "Authorization": `Bearer ${auth.userData.access_token}`
    }
  ))

  const res = await promiseClient.list(
    request,
    {
      headers: headers
    }
  );
}

Bellow the browser error:
