We’re experiencing some random disconnections in the process for Exchange of Refresh Token for Access Token.

This is the error that we found in the log:

  "date": "2022-04-05T10:17:01.087Z",
  "type": "fertft",
  "description": "Cannot read property 'scope' of undefined",
  "connection_id": "",
  "client_id": "XXXXXXXXXXXXXXXX",
  "client_name": "App",
  "ip": "xxx.xxx.xxx.xxx",
  "user_agent": "Company 4515.0.0 / Other 0.0.0",
  "hostname": "xxxxx.eu.auth0.com",
  "user_id": "",
  "user_name": "",
  "auth0_client": {
    "name": "react-native-auth0",
    "version": "2.1.0"
  },
  "log_id": "XXXXXXXXXX",
  "_id": "XXXXXXXXXXXX",
  "isMobile": false
}```

Any ideas?

Hi @miguel.hernandez ,

Welcome to the Auth0 Community!

I checked your tenant and noticed in the rule “Basic Scope Verification”,

const requestedScopes = context.request.body.scope || context.request.query.scope || '';

Do you want to try updating it as below and check the log again?

var requestedScopes = context.request.body.scope || (context.request.query && context.request.query.scope) || null;
