Hi 

I’ve just upgraded our development repository from eprints 3.3.12 to 3.4.3 using the rpm (and default flavours tar file) migrating the changes across as in https://wiki.eprints.org/w/Upgrading_3.3.12%2B_to_3.4 and applying patches/changes as described at https://wiki.eprints.org/w/EPrints_3.4.3#Known_Issues. I’ve hit an issue with the RIOXX2 plugin, whenever I try to edit an item I get a “500 internal server error” before anything is rendered in the browser. The apache log shows

[Tue Jan 11 16:34:41.454113 2022] [:error] [pid 2830] Can't call method "isa" on an undefined value at (eval 222) line 8.\n at (eval 222) line 8.\n\t

If I disable the plugin the page renders successfully without the rioxx2 tab, if I disable the following:

$c->{plugins}{'InputForm::Component::Field::RIOXX2'}{params}{disable} = 1;

in my local archives zz_rioxx2.pl the edit item page displayed but links to License ref field, Accepted Date and Project are only rendered as text and not a full link, I’ve checked that all the plugin files are where they should be and have even removed and reinstalled the RIOXX2 plugin and the internal server error still happens

Has anyone come across something like this before?

Thanks
