OC 20.3.2 hangs up while displaying snmp tab via groups

[Stefan Pivoda]

the OC hangs up while trying to display Group/random group/random device/SNMP tab in UIM/OC 20.3.2, and the wasp generates the error logs copied below.
after that only wasp restart helps to reach OC again.

if i try to display the SNMP tab via Inventory, eveything works correctly.
i noticed this behavior in 2 different UIM 20.3.2 environment.
if i remember it correctly, i could display the SNMP tab in this way in the previous 20.3.1 version.
do you have it as well please = is it some bug or is it some issue only in our configuration? if so, how to fixt it please?

From a general perspective there have been some new updates for 20.3.2 posted at the hotfix site, would start there along with ensuring they all have robot_update 9.32 deployed.
