On provider error return it as an answer

[4www]

When making a query to the providers api, if there is an error, return those error messages as the media api response.

Should it it be the pure "provider' error message, or should it be a "unified" message thought every providers available?

I am thinking maybe both with something like that:

{
  error: {
    code: '404',
    message: 'content not found',
    providerError: { // raw provider error}
  }
}

What error to return?
