On almost all servers this is a simple configuration change to fix (or of course, you could stop sending so much metadata in your requests), but if you're not logging client errors then you won't notice this on the server side at all. For many cases that isn't possible though (for 3rd party clients and applications merely using your SDK), that may comes with serious privacy risks (for clients running on user devices), and reporting client errors from the server directly can make issues more directly available to the team best placed to deal with them.
