Mapping laravel validator errors in JS

Question

My API returns validation erros with a object like:

{
"message": {
    "cnpj": [
        "The cnpj field is required."
    ],
    "nome": [
        "The nome field is required."
    ]
}

}

How i can map each object for a console.log() or li method using pure vanilla JS?

Had tried using error.response.data.message but no success, because message is an object.

try:

Object.entries(error.response.data.message)
  .map(([, fieldErrors]) => 
    fieldErrors.map(fieldError => <li>{fieldError}</li>)
  )

Object.entries convert an object to an array containing [key, value] for every key in an object, meaning:

let obj = {a: 1, b: 2}
console.log(Object.entries(obj)) // will become [['a', 1], ['b', 2]]
