Seems to be caused by an empty plugins tag in the config. Needs to be updated to use the new accessor method.

Any idea how that bad tag made it into the configuration?

That isn't something we've seen in any testing before that I'm aware of.

Sorry for not including more detail on the creation.

This is a customer config. They went from 2.6, on a fresh install, to 23.05 and restored their backup. The empty plugin tag is in the squid package section.

They must have hit some other older bug first. At least on a current install, the squid package has two plugins listed (plugin_carp and plugin_certificates) and not an empty tag. There was an older bug some time ago that could lead to empty tags in certain cases, but it's been fixed for some time.

Not saying we won't fix this, but that it's hopefully a rare situation and not widespread.
