error is a reserved word in some programming languages. Also it makes it easier to search retrieved error responses

Do you think this is an advantage? I think the main problem was showing the correct errors from the LCD and not sth like 500 The server produced and error.

The correct errors from the LCD are fixed on the SDK. The missing part was verifying that we didn't append any additional message on top of them
