Subject: [PATCH] fix: `invalid_input` API errors may not return details

The create uploaded certificate endpoint may return the following error:

{
  "error": {
    "code": "invalid_input",
    "message": "certificate must use larger key size"
  }
}

This change ensure that we do not get a json unmarshal error (unexpected end of json) while trying to parse a non existing data.
