That's exactly what the error says, but I don't think that's what she wants. I've had situations where the data wasn't getting saved into the Json format and sent a null. The correct route was called, but no data got passed in. So, having no data would just do nothing. Isn't she trying to save data here? That's why I suggested using Alert dialog to see what data is being passed around.
