@froemken
Thanks for reporting that issue.
I can not reproduce this issue currently within solr-ddev-site
ON:

• TYPO3 11.5.19 + 21
• PHP 8.1.8
• EXT:solr 11.5.0, release-11.5.x@01d568b

Could you please check if #3427 resolves this issue?

Hi @dkd-kaehm

yes, this will solve the issue, too.

The return value of BU::getRecord() is array|null that's why I thought you will add a test for array instead, before accessing the array value one line below.
