The error is thrown in the purge module, but only happens when the varnish image purge module is also enabled.

After further investigation this is not from the varnish image purger, it's the varnish purger module in general, if there is a varnish purger enabled then it fails.

This also occurs on config import if there is config to import. If there are no config changes config import is fine.

Thanks for the report. I never had this issue myself, do you have steps to reproduce the error? Which version of the Purge module are you using?

For me it occurs when I have a cache tag invalidation set to an ip address with ban requests and then run a drush command that accomplishes something.
E.g. drush cim when there are config changes to import, updb when there is a database update or cron when there is a batch to process.

I am using the following:
queuers
core tags, p:queue-add, Purge blocks

Queue
database

Processors
p:invalidate, p:queue-work, Purge blocks

This only started after updating to Drupal 10 and Drush 11.
I am using drupal/purge 3.5
I am using drupal/varnish_purge 2.2.0

@Nicxvan, Maybe it is related with this issue and you have, like me, a patch applied?
