Conversion issue on Linux (GroupDocs.Conversion for .NET)


I am trying to run the conversion on Linux.
It works fine on Windows but on Linux I’m getting an exception:

Error Message:
GroupDocs.Conversion.Exceptions.GroupDocsConversionException : Object reference not set to an instance of an object.
Stack Trace:
at \u000f\u0005\u0003.\u0002()
at GroupDocs.Conversion.Converter.\u0002()
at GroupDocs.Conversion.Converter.Convert(SaveDocumentStream document, ConvertOptions convertOptions)

API version: GroupDocs.Conversion 22.7.0
Linux version: Ubuntu 20.04.4
Expected output file format: PDF
Files to convert:
TestFiles.zip (950 Bytes)

Thank you,


Could you please share the sample code/application as well?

I cannot share the code with you, but created a sample solution to show how I do the conversion. Please take a look at the unit test. This test works on windows locally but fails on gitlab pipeline (Ubuntu 20.04.4).
