javascript - Eroarea următoare a provenit din codul tău de test, nu din Cypress

Mă confrunt cu această problemă atunci când rulez testul Cypress, aceasta este eroarea care provine de la Cypress **Următoarea eroare a provenit din codul testului tău, nu din Cypress.

Nu se poate citi proprietatea 'firstName' a unui obiect nedefinit

Când Cypress detectează erori negestionate care provin din codul tău de test, va eșua automat testul curent.

Cypress nu a putut asocia această eroare cu niciun test specific.

Am generat dinamic un nou test pentru a afișa această eroare.

Verifică consola pentru urmărirea stivei sau fă clic pe acest mesaj pentru a vedea de unde a provenit.

Și acesta este codul meu
