We are testing the HosatAP module integrated with MBedTLS version 2.19.1. But we are receiving an error during the SSL handshake. In Server side we are using hostapd daemon - we see the below error:

As you can see the Session Ticket details are missing and that Length 0 field is the last byte in the message but still in Wireshark we see other details like JA4, JA4_r etc?

Is the "Client Hello" response from the client in the correct format?
