"Error! Bar code generator is not set." rendered instead of actual QR code converting DOCX to PDF in .NET

GroupDocs.Conversion Product Family

Converting the attached file to PDF only renders “Error! Bar code generator is not set.” instead of the QR/Barcode using GroupDocs.Conversion 23.4.

About a year ago I reported the same problem for the Viewer:

Additionally I noticed that the fields (custom document properties) are not updated anymore:

The “updated” column should show say “hello world”, as it did in previous versions:

Can you please take a look at this issue?

I’ve attached different outcomes generated by different GroupDocs.Conversion versions.
Getting back the state from 22.6 would be the desired behavior. Scaling was broken with 22.9.

We’re planning on upgrading, but we’re currently still using .NET Framework 4.7.2.

Thank you for the fix. I can confirm that it’s working fine now with GroupDocs Conversion 23.5.
However it’s somehow not working with GroupDocs.Total 23.5, which should include that Conversion 23.5 version according to description. I saw the old behavior with the barcode error.

It’s also not working when combining GroupDocs.Conversion 23.5 and GroupDocs.Viewer 23.4 in the same project (same versions as in GroupDocs.Total).
When attempting a conversion with the viewer, I get this unhandled exception:

System.TypeInitializationException: 'The type initializer for ‘ ’ threw an exception.’
Inner Exception:
InvalidOperationException: Operation is not valid due to the current state of the object.

I’ve attached my test projects, can you please take a look?

Using GroupDocsTotalProblem we cannot reproduce any issue. Could you please share a screenshot?
However, with the project GroupDocsMixedProblem we could reproduce the issue.
One possible workaround is to install Aspose.Words v23.3 in the project. This makes the project run. The other option is to wait for GroupDocs.Viewer v23.5.

I tried to reproduce the issue again today and I’m also unable to do so.
So I think the problem with GroupDocs.Total was only a temporary issue on my side.
Thank you for checking!
