Maybe not the best bug report, but its a start.

On ProxmoxVE Scripts repo, there is a problem, when installing browserless.

community-scripts/ProxmoxVE#8127
community-scripts/ProxmoxVE#8001

It seems, that this installation bug should be reported here.

So - i will do this.

I am sorry, that i am not technically so deep into it, that i can write you a good bug report, but maybe it helps you, to read the both issue links.
