Can you expand the packet in Wireshark and see what it is complaining about?
We may have introduced a bug in our copy of libcoap.
I hope it's only complaining about the format of the body. Since we use CBOR,
wireshark probably won't understand it.

5.00 is "Internal server error". You said that you didn't see the packet on
wireshark, but coap-client is showing a reply. So either wireshark failed to
show something or coap-client didn't send anything. I can't go from here, I
need more information.
