OID Can not be found with SNMP v3 Lib

Hi,

Firs't I'd like to thank @semihiseri for his Library GitHub - semihiseri/libSNMP: SNMP v2c/v3 Agent Library for Arduino regarding SNMP v2c and V3 and I am trying to test it in my ESP32 POE board and I just replaced the ehternet library to be work and I can get the ip address but in serial monitor I found these:

ETH Connected
ETH MAC: C4:4F:33:64:D1:40, IPv4: 192.168.43.132, FULL_DUPLEX, 100Mbps
Engine id: 1 2 3 4 5 6 7 8 9 0 D0 D0 D0 D0 D0 D0 D0 D0 D0 D0 done
privKey is: EC A0 19 1 7A 89 49 3A E E8 E9 12 F2 CA F8 9F 
OID can not be found
OID can not be found

and also I installed SNMPpower to detect the agent but didn't find the agent, and I put the same user and passwords but didn't work with me!

How can I let it work?

Any help for that!
