ssl decode error 41

[debugger2]

Hi. I have this error issue when try to use keylogger for ssl decription
SSL decode failed: err code -41, connection client_ip->server_ip

i see how keylogger send session keys to voipmonitor like

SSL KEYLOG[18188]: send key : SERVER_HANDSHAKE_TRAFFIC_SECRET a7018bd9c9e00f3761fb5d531fd860277f3f5e648aa59391416ab6acb4acd33a 2ae85d11119b8a7c062a7f26610d53f87bb82de3af14abcacb113f23b5ec4277 (size: 161)

but voipmonitor show error and make database record like

{"version":772,"cipher_suite":4865,"compression_method":0,"client_random":"B24B103C650D7EE87469A4D6E51B43EC354A028972A4AE7ED6F8F0F0DDD8504B","key_client_random":"","key_client_handshake_traffic_secret":"","key_server_handshake_traffic_secret":"","key_exporter_secret":"","key_client_traffic_secret_0":"","key_server_traffic_secret_0":"","seq_server":0,"seq_client":0,"c_dec_version":769,"s_dec_version":771,"stored_at":1637049321}
