@JJ Thanks for reaching out. As mentioned in SelectPdf docs:
SelectPdf Html To Pdf Converter (v18.3) or above works on Azure Web Apps, on Windows, and an App Service Plan starting with Basic (does not work with Free/Shared plans). Using a Standard or Premium plan will make conversions faster.
The Web Apps version uses a restricted rendering engine and because of that, some features are not available. To name a few: no support for web fonts, support only for single page PdfHtmlElement objects, no support to exclude elements from conversion.
Please check if the following helps:
- Could not get conversion result header. Data transfer error. Data transmission error 109
- Upgrade to the latest SelectPdf library
- Troubleshooting
If the error persists, request you to open an issue with SelectPdf on GitHub here: https://github.com/selectpdf/selectpdf-free-html-to-pdf-converter/issues/
