ManagementClient is not a constructor

I am unable to use the auth0 Node.js client library from within Rules.

I get the following error:

 (node:6) UnhandledPromiseRejectionWarning: TypeError: ManagementClient is not a constructor

example code:

    global.getRoleIdsByName = global.getRolesByName || async function (role_names) {
        const ManagementClient = require('auth0').ManagementClient;
        const management = new ManagementClient({
            token: auth0.accessToken,
            domain: auth0.domain
        let roles = await management.getRoles();
        return roles.filter(role => role_names.includes( =>;

Note that this works just fine when executed from a local Node.js environment like my IDE.

I have seen this library being used (example) hence my confusion …



for anyone else having struggled with this apparently adding the version fixed the problem:

const ManagementClient = require('auth0@2.23.0').ManagementClient;

Perfect! Glad to hear that and thanks for sharing it with the rest of community!
