We have recently updated our aspose library to R22.8 because of a .NET 6 migration, but are encountering severe errors with the library.
Seems like this issue is happening only in Linux while Windows works:
Our test environment OS is ubuntu focal with .net 6 SDK
Test method XXXX.XXX.XXX.Output.UnitTests.Aspose.PdfDocumentGenerationTests.CanGeneratePdfWithTextFragmentToFile threw exception:
System.ArgumentNullException: Value cannot be null. (Parameter ‘key’)
