This issue seems to come back every now and then:
#2557

We ended up adding this to our pipeline"

# Oryx uses an outdated version of Poetry, so we manually install the latest version.
# Sometimes this issue still occurs:
# https://github.com/microsoft/Oryx/issues/2557
# We can remove this once they support Poetry 2.0+.
curl -sSL https://install.python-poetry.org | python3 -
# Export requirements.txt file which will be picked up by Oryx
/home/.local/bin/poetry self add poetry-plugin-export
/home/.local/bin/poetry export --format=requirements.txt --without-hashes --output requirements.txt

And gave up hope that Microsoft will actually fix this within the upcoming gazillion years.
