Option --biber doesn't produce a diff for bibliography
Hello,
I am trying to display differences in the bibliography using a minimal example. "Normal" differences in text are displayed correctly.

file test.tex
1 \documentclass{scrreprt}
2 \PassOptionsToPackage{%
3 backend=biber,bibencoding=utf8, %instead of bibtex
4 language=auto,%
5 style=numeric-comp,%
6 sorting=nyt, % name, year, title
7 natbib=true % natbib compatibility mode (\citep and \citet still work)
8 }{biblatex}
9 \usepackage{biblatex}
10 \addbibresource{test.bib}
11 \begin{document}
12 \nocite{*}
13 \printbibliography
14 \end{document}
<br>
<br>
file test.bib (HEAD^)
1 % Encoding: UTF-8

3 @Book{test,
4 author = {Author},
5 title = {Title},
6 year = {2019},
7 date = {2019-09-07},

Invocation of git-latediff:
`git-latexdiff --main test.tex --append-textcmd=field --biber --flatten HEAD^ HEAD`
I also tried without --flatten and without --append-textcmd=field. But these were recommended in the following link: [tex.stackexchange.com](https://tex.stackexchange.com/questions/167064/latexdiff-changes-in-bibliography-with-biblatex-and-biber).
Also, i made sure the .bib, .bbl files are included in both git commits.
Output pdf file:

What am i doing wrong?
