Authors are not included in book reference

[ramojus]

If I have a book reference in .bib file like this:

@book{programmingBC19AL,
  author={Marije Brummel and David A. Studebaker and Christopher D. Studebaker},
  title={Programming Microsoft Dynamics 365 Business Central},
  edition={6},
  chapter={Introduction to Business Central},
  eil={AL programming language},
  year=2019,
}

typst with default citation style (IEEE) renders the reference like this:

Zotero with IEEE style renders the reference like this:

From my experimentation, it seems like the author variable is empty in csl if used for book type reference.

My further experimentation shows that this only happens when chapter is set in .bib file.
