Return the key of the object, in the array of which a match was found with the error that was passed, what am I doing wrong?

Question

JavaScript

There is an object:

const obj = {
  defaultError: ['A1', 'A2'],
  redirect: ['B1', 'B2']
}

Iterate through each value and if there is an entry in the array that is equal to an error, return that key (defaultError)

Wow, you're not the only one today who doesn't know that forEach doesn't return anything.
Rewrite your code so that it works as it should , for example.
