I am encountering an issue with PDF generation in ERPNext 15 hosted on a DigitalOcean server running Ubuntu 24.
When trying to generate a PDF, In a Print Format generated with WeasyPrint, I receive the following error:
TypeError: PDF.__init__() takes 1 positional argument but 3 were given
This error occurs in the pydyf.PDF() function, which is being called by WeasyPrint. I am currently using the following versions:
- WeasyPrint: 59.0
- pydyf: 0.10.0
- erpnext: 15.30.0
- frappe: 15.35.0
Many Git Discussions are leading me to this link, but I don’t understand what It is trying to say: https://github.com/Kozea/WeasyPrint/issues/2200
I also attempted upgrading WeasyPrint, but encountered the following dependency conflict:
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
frappe 15.35.0 requires WeasyPrint==59.0, but you have weasyprint 61.0 which is incompatible.
I’d appreciate any insights or suggestions from the community regarding this error and potential compatibility issues between WeasyPrint and pydyf.
If I have missed to mention anything and more details are needed, please let me know.
