Error on Raspberry PI testing with macOS 14.4 (previously working on macOS 14.3.1):

Hey @pjs7! I encountered this same issue, and discovered that this happens because iOS seems to be sending its /Discover post bodies via Transfer-Encoding: chunked, which doesn't include a Content-Length header. Some WIP code to handle it is in a draft PR at #116
