ReferenceError: setImmediate is not defined

I am using next.js project with typescript.

I am facing this issue when jest tries to run the mock file

ReferenceError: setImmediate is not defined

in the file __mocks__/elasticsearch.ts

import { Client } from '@elastic/elasticsearch';
import Mock from '@elastic/elasticsearch-mock';

const mock = new Mock();
const client = new Client({
  node: 'http://localhost:9200',
  Connection: mock.getConnection(),
});

mock.add(
  {
    method: 'GET',
    path: '/',
  },
  () => {
    return { status: 'ok' };
  }
);

client.info(console.log);

Hi,

I am having the same problem as @railsfactory-vishnuroshan in a node JS project, same configuration, same error. Has somebody solved this error?

Thanks for your help.

Hello! Very likely Jest is doing something weird behind the scenes and breaks the client code.
See jestjs/jest#2549.

Hi All,
This issue is due to test environment, if you are using --env=jsdom you will get this issue.
Please try to remove this --env=jsdom or use --env=node
