h.bibliography.push is not a function

lks

Hello,

I am trying to make Zettlr export my file with XeLateX, but it is throwing this error:
h.bibliography.push is not a function
I'm running the .rpm on Fedora 42, connected to Zotero with BetterBibTeX exporting to CSL-JSON. I can export the document with simple-pdf and it exports and the citations show up fine. This issue has come after I have fixed issues with a missing parskip package. Anyone has seen this error before? Here is my defaults file:
