It’s a sandbox. I found this information on this site https://github.com/projectkudu/kudu/wiki/Azure-Web-App-sandbox#pdf-generation-from-html

PDF generation from HTML

There are multiple libraries used to convert HTML to PDF. Many Windows/.NET specific versions leverage IE APIs and therefore leverage User32/GDI32 extensively. These APIs are largely blocked in the sandbox (regardless of plan) and therefore these frameworks do not work in the sandbox.

There are some frameworks that do not leverage User32/GDI32 extensively (wkhtmltopdf, for example) and we are working on enabling these in Basic+ the same way we enabled SQL Reporting.

I think i cannot use this module in my situation.
