Getting error in generating the PDF from wkhtmlpdf

Question

• I am generating the PDF from command line DocFX.exe. In same folder I kept wkhtmltopdf.exe to generate the pdf.

• The cmd to generate the html documentation works correctly, but I'm getting error in generating the PDF.

• I am using one docfx.json file which keep the configuration. docfx.json contains the pdf section also.

• Inside pdf section, I am using the default template in pdf section.

  "pdf.default",
  "docfx/templates/default"
  

Getting error in generating the PDF from wkhtmlpdf:

Error: ArgumentException: Invalid manifest item: Microsoft.DocAsCode.Plugins.ManifestItem
