.Invalid URL-encoded text from the client no longer creates errors Previously, the system improperly handled scenarios where URL decoding resulted in an empty `key.name`. The empty `key.name` due to invalid URL-encoded text from the client. As a result, an assertion error during the copy operation would occur, and sometimes led to a crash later. With this fix, invalid empty `key.name` values are now ignored, and copy operations no longer trigger assertions or causes crashes.
