Hi Guiseppe, these system preferences have a different purpose. The internally used API routes should work without changing any configuration. This is most likely to be an installation/dependency issue. The acquisition error you reported also points in this direction, it's all symptoms of the same problem. I think others can help better here, but this information would help: You have a package installation on Ubuntu 18.04 LTS? What does your entry in etc/apt/sources.list.d/koha.list look like?

Hi, Katrin.

...

the patron search in 22.05 was changed over to use the API for searching. I think the API is not working correctly for you.

In fact, after looking for "API" among the Koha Administrative Interface paraments, I noticed that RESTBasicAuth and others were "disabled" for me.

After enabling them, the patron search function works as always!

Now, I suspect that a problem I reported in Nov 2021 and that you, Katrin, kindly filed as a bug in:

https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=29581

has to do with the same new feature. Namely, I cannot presently find any unreceived shipment, even though there are plenty items expected.

(Enabling RESTBasicAuth wasn't enough for that.)

So many thanks!

Giuseppe.
