Im trying to run the example code in https://www.npmjs.com/package/@chirpstack/chirpstack-api/v/3.12.4 , I had to add .js in the en of the imports, but Im still getting errors, Im getting:

^

TypeError: internalMessages.LoginRequest is not a constructor

Im running the code on VSC, whit Code Runner and JavaScript (ES6) extension, I have Nodejs installed
Im posting this here because Im using the code provided by chirpstack.
Beforehand thank you very much

I am getting the same error too. The example code must be really old. I had to change the imports:

import * as internalService from '@chirpstack/chirpstack-api/as/external/api/internal_grpc_pb';
import * as internalMessages from '@chirpstack/chirpstack-api/as/external/api/internal_pb';

to

import * as internalService from '@chirpstack/chirpstack-api/api/internal_grpc_pb.js';
import * as internalMessages from '@chirpstack/chirpstack-api/api/internal_pb.js';

but I am still getting the error “internalMessages.LoginRequest is not a constructor” at this code:
const loginRequest = new internalMessages.LoginRequest();

Did anybody found the solution for this error
