SNMP V3 errors

[Renny]

Good morning friends!
I'm finding it difficult to monitor a Vcenter esxi 6.7 and the hosts managed by it through SNMP V3 and configure the traps. After making the connection with the environment to be monitored, the traps and intens return with the following messages, respectively:
"Preprocessing failed for: []
1. Failed: cannot extract value from json by path "$..['{#CPU.UTIL}'].avg()": cannot apply aggregation function to empty array"

and

" No Such Object available on this agent at this OID "

Does anyone have any idea what it could be?

Hello!
I continue to find it difficult to monitor a Vcenter esxi 6.7 and the hosts managed by it through SNMP V3 and configure the traps. After making the connection with the environment to be monitored, the traps and intens return with the following messages, respectively:
"Preprocessing failed for: []
1. Failed: cannot extract value from json by path "$..['{#CPU.UTIL}'].avg()": cannot apply aggregation function to empty array"

and

" No Such Object available on this agent at this OID "

Grateful.
