I posted  today. If that's accepted I can work on Rocky afterward.

Could you open a bug with more details about the issues you're hitting.
Like in what case do you hit ComputeHostNotFound?
The sequential errors thing is pretty obvious but I'm not sure what to
do about it off the top of my head besides some option to say "process
as much as possible storing up all of the errors to dump at the end"
kind of thing.
As for better logging about unexpected errors, it's hard to know what to
log that's better when it's unexpected, you know? If you have examples
can you throw those into the bug report?
