Hello there,

We're using the EO components 23.1.77.0 I'm experiencing a crash when attempting to convert around 1,400 HTML files to PDF. We were able to process(convert to PDF) a few hundred records but after updating from 18.0.15.0 to 23.1.77.0 we are 18.0.15.0encountering the error below. When using 18.0.15.0 we were able to process over 4,000 records.

The exception stack trace we got from the last run were:

Any advice you can provide to overcome this issue is appreciated.
Please let me know what I can provide to look into this further.

Many thanks,
Ivan Castillo

I did some preliminary testing using the latest version of the library as you recommended but still keep getting the same error description shown initially (System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> EO.Pdf.HtmlToPdfException: WebView has failed ---> EO.Internal.bavp: Failed on command 5:), Is there any additional suggestion or insight that you can provide us to overcome this issue?

Hello,
We already have the crash log but we are concern that it might contains personal identifiable information, or other proprietary information related to our company property. Can you tell us if the file contains any PII? Also, do you have a more secure way for us to send you the file instead of using this public forum?

Thank you!

Thank you for your assistance. We ended up upgrading to the latest version available of the dll, but what seems to have made the difference in the process completing successfully was following your suggestion to add the following code to the start up code of our application:
EO.WebEngine.EngineOptions.Default.DisableGPU = true;

This advice, came as because one of the crash log showed that it is not able to initialize a GPU device.
