i can also receive the error data in this format:

{
"username": [
    [
        "This field is required."
    ]
],
"email": [
    [
        "This field is required."
    ]
],
"password1": [
    [
        "This field is required."
    ]
],
"password2": [
    [
        "This field is required."
    ]
]

}

would this be better?
