[Rishabh242002]

In payload after submitting form:

picture: [object File] occupation: Fake Con Man location: Fake Location, CA password: fake_password email: fakeman@gmail.com lastName: man firstName: fake picturePath: undefined

Can you explain it ?

[topslugBurpy]

set the initial value of picturePath to null rather than an empty string
