html to pdf running on azure windows vm not working

[Rakshit Shah]

Hi,

I am using HtmlToPdfConverter class with "QtBinariesWindows" to convert html to pdf developed with dot net core 3.1 LTE. 

I have deployed my application to Azure VM  Standard D2s v3 (2 vcpus, 8 GiB memory) windows machine. 

At time of conversion I am getting below error: 

Error Detail: Syncfusion.Pdf.PdfException: Html conversion failed

Please do the needful. 

Thanks,

Rakshit Shah

Hi Rakshit, 

 

Thank you for using Syncfusion products.  

  

We have checked the reported issue with provided details, the reported issue may occurs in following cases,  

 

Cause	Solution
Using Free/shared hosting plan	While hosting the application in Azure, the converter may throw an exception under Consumption/Free/Shared hosting plans on Azure. Due to the access restrictions and limitation of these hosting plans, it prevents the loading of the browser process. So, the conversion will be failed in the Consumption/Free/Shared hosting plans on the Azure environment. Other hosting plans do not have the restriction for loading the browser process. Please try the conversion with Basic (B1) or above hosting plans and let us know the result.
QtBinaries file not shipped properly	Please make sure the all the files from QtBinaries folder are shipped to Azure app service environment using console in Azure portal. If some are missing, kindly include them manually and try the conversion.
Deploy option	If you are using Run from package option, the reported issue may occur. So, can you please try the conversion without run from package option while deploying the app to azure app service.
Using zip deploy options	WebKit rendering engine will not work in zip deploy options, so kindly try the conversion without zip deploy option.

  

Note: Kindly make sure you are using the hosting plan from Basic (B1) or above mentioned hosting plans to publish on the Azure environment. Also please check with a simple conversion like (https://www.google.com ) on your end and let us know the result.
