Looks like there is some caching issue

1. Launched 2 vms ( vm1, vm2)

2. Take a vm snapshot with disk and memory for vm 1

3. Take a vm snapshot with disk for vm 2

In a incognito window, try to delete the vm snapshots ,we get the same error message

@kiranchavala I think there might've been an issue with the version that I was basing this PR on. I have merged the main branch on my branch and tested and it looks good. Could you test again?
If you find an issue, could you detail which steps you took to get to the issue?

@JoaoJandre
is this still applicable ?
which branch should be targeted, 4.22 or main ?
