OpenHtmlToPdf.netcore not working on linux

Question

I switched to linux and since then the OpenHtmlToPdf stoped working. I was getting the permission error, I changed the permission for the file that was giving the error and worked, but now I am getting another error that returns a base64 that says "Platform Unix is not supported". How can I get this to work again?

Answer 1

the library uses the wkhtmltopdf command line tool.:

https://wkhtmltopdf.org

the nuget package includes the windows version of the tool (OpenHtmlToPdf.WkHtmlToPdf.exe). you will need to replace it with a version that supports your o/s.

https://wkhtmltopdf.org/downloads.html

note: the exe name is hardcoded to "OpenHtmlToPdf.WkHtmlToPdf.exe", so you may need to rename to match.
