"Slot Swap" operation randomly change slot host keys

[lipalath-ms]

Hi,

I'm doing deployment to functionApp slot (+ my custom script to enable managed identity on all slots and update app settings with values from keyVault) in my Azure Devops classic pipeline and then swap slot operation with "Azure App Service manage" task. Unfortunately, swap randomly changing host keys on my slot, which is causing 401 in other places. They are always swapping between two sets of host keys, one set which is a copy of functionApp prod slot (with one custom host key), and second, set with only _master and default keys.

How to prevent changing hostKeys on my slot?

Investigative information Please provide the following:

Function App version: 4.12.2.19454 Function App name: gmm-data-int Region: West US 2
