Error

I am getting the following error:

File "/usr/local/lib/python3.10/site-packages/weasyprint/layout/inline.py", line 1143, in text_align
    assert align == 'end'
AssertionError

Just by using the table class from Bootstrap.

System Information

  • OS: alpine3.15
  • Python: 3.10.3
  • Weasyprint: 54.2
  • Bootstrap: 5.1.3
