EDIT:
Looks that this line cause problems

EMBEDDED_FILE = HERE / "requirements.txt"

Hi @qarmin

This is absolutely not a bug.
We simply have a unit test relying on the content of this file:
https://github.com/PyFPDF/fpdf2/blob/master/test/test_embed_file.py

A simple text search in the test/ directory would have easily revealed that.

This simply means that if you modify the content of test/requirements.txt in a PR,
you must re-generate the reference PDF files for test_embed_file.py,

Our documentation dedicated to code contributors will provide you explanations on how to do so:
