Receiving "security service 3 error parsing ScopedPDU" in trap with AES-256 as priv protocol

Question

I am trying to receive pysnmp trap message with SHA/MD5 and AES-256. I can receive AES-128 trap but I am unable to log AES-256 priv traps. Here is the error for each PDU generated in snmptrapd.log

NET-SNMP version 5.9.3
security service 3 error parsing ScopedPDU
security service 3 error parsing ScopedPDU

I am able to log traps normally with other settings. Here is my entry in snmptrapd.conf.

createUser -e <engine_id> test_user SHA "password" AES-256 "password"

I am able to capture packets in wireshark which gives following after entering credentials(username and password).

Please let me know what I can change in config to log the traps.
