Account Linking Error "Cannot find module 'request@2.56.0'" when Using Node 18

This article explains the below error from the Account Linking Extension in a tenant using Node 18:

Cannot find module 'request@2.56.0'

This also triggers a "Failed Login" log in the Auth0 dashboard with the error message.

NOTE: This error gets thrown after a user authenticates and the Account Linking Rule, generated by the extension, is attempting to run.

• Node 18
• Account Linking 

The Account Linking Extension uses an older version of the request NPM package which is not compatible with Node 18.

There are two possible solutions:

1. Switch the tenant to Node 16 by going to Settings > Advanced > Extensibility section in the Auth0 dashboard.
2. If there is a requirement to keep the tenant on Node 18, then it should be possible to amend the Rule with the changes below: 

     //var request = require('request@2.56.0'); //Comment this line
     var queryString = require('querystring');
     var Promise = require('native-or-bluebird@1.2.0');
     var jwt = require('jsonwebtoken'); //Remove version targeting

   request is embedded in the runtime environment, and jsonwebtoken needs the targeted version removed.
