Format exception on Azure while converting docx file to pdf

[phil.plund]

I have this piece of code for converting a docx file to pdf

Code: Select all

   
                Spire.Doc.Document document = new Spire.Doc.Document();
                document.LoadFromFile(docxFilePath);
                document.SaveToFile(pdfFilePath, new Spire.Doc.ToPdfParameterList()
                {
                    UsePSCoversion = true
                });


Worked fine on local but when I deployed to Azure web app service, it threw exceptions messages (pls see the attachment)
**Already setting up license on Startup.cs
Using pro. edition - Spire.Doc 9.6.1


Could anyone help me out ?
Thanks!

Is there any update on this issue?

We recently upgraded our Spire Azure function from version 7 to the latest 9 and got the same error message.

Version 7.12.23 seems to be the last working version (.NETCoreApp, Azure Function V3)

Code: Select all

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <AzureFunctionsVersion>v3</AzureFunctionsVersion>
    <RunPostBuildEvent>OnBuildSuccess</RunPostBuildEvent>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="3.0.13" />
    <PackageReference Include="Spire.Doc" Version="7.12.23" />
  </ItemGroup>

Unfortunately it still crashes with a System.NullReferenceException: 'Object reference not set to an instance of an object.'
Running Spire version 9.8.6

After the Exception my whole function crashes with an AccessViolationException on anything else I do (trying to log the previous error).
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Thanks for your feedback.
I tested your case with the Word file "F-2021-116976.doc" you provided to us before, but I did not encounter any issue when using the version 9.8.6.
Are you encountering this issue while testing other files? If so, please provide us with the corresponding files to help us investigate further. Thanks in advance.
