Can't print Shipments

[Pekkonen]

I have site based on Magento ver. 2.4.3-p1
with installed magento-2-font-pdf-invoice and when I trying to print any Shipments (Sales-Shipments-View-Print) I have an exception:

There has been an error processing your request
Exception printing is disabled by default for security reasons.
