When the SDK request fails, the
error field returned is not empty, but instead includes an error code, error description, and other necessary debugging information to help developers quickly fix any issues. Error codes (outlined in the returned error field) include those returned by the client and those returned by the server.Client Errors
Error codes generated by your device due to network problems are all 4-digit negative numbers, such as -1001. These error codes are defined by Apple. For more information, see the definitions presented in the header file
