External task js problem to pool https urls

DaniMadmolil · February 3, 2023, 8:37pm

I use external camunda-external-task-client-js to setup a service task for deployed camunda tomcat with ssh setup.
get error : * polling failed with RequestError: unable to verify the first certificate
tanks.

import {
  Client,
  logger,
  BasicAuthInterceptor,
  Variables,
  File,
} from "camunda-external-task-client-js";

const basicAuthentication = new BasicAuthInterceptor({
  username: "username",
  password: "password",
});

const client = new Client({
  baseUrl: "https://xxx/engine-rest",
  interceptors: basicAuthentication,
  use:logger
});

client.subscribe("topic-name", async function ({ task, taskService }) {

}

but i get this error in console :

polling failed with RequestError: unable to verify the first certificate
tanks.

// configuration for the Camunda Client:

//  - 'asyncResponseTimeout': long polling timeout (then a new request will be issued)

//  - 'maxTasks': The maximum number of tasks to fetch from Camunda in batch
//  - 'maxParallelExecutions': The maximum number of tasks to be worked on simultaneously
//  Number of async execution threads = maxTasks if maxParallelExcecutions is not set
//  Else Number of async threads = min (MaxTasks,maxParallelExcecutions)

const url = process.env.CamundaUrl || 'http://camunda:8080/engine-rest';

Try use ssl interceptor in worker procedure, with registering self signed root certificate.
