Biblatex tells me \addbibresource was never defined

Sat Feb 8 13:57:58 UTC 2020

I am using LyX 2.3.4

I set it to Biblatex in the GUI, but it tells me \addbibresource was
never defined. (See the two documents attached.)

Anybody has a clue why? I am out of ideas...

Bernd

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.
