Verify works but throws error

Finally got a working solution with a Vue(2.6)/Vuetify(2.3) using Node for authentication. After a push request, verify_response returns back the given user name but also throws an error “TypeError: Cannot read property ‘split’ of undefined”

It’s only returning the username - what else would should it be returning that it’s trying to split for me?

Is it safe to ignore that error?

The full error is at

TypeError: Cannot read property ‘split’ of undefined
at Object.verify_response (C:\en\node\node_modules@duosecurity\duo_web\duo.js:176:28)
