CellsException: Map size (0) must be >= 1


I’m trying to convert an excel document to PDF. When I do I get the following error and the pdf is created but empty. The file can be opened with Libreoffice and of course Excel.

We’re using aspose-cells.jar (7.4.3)

The error is:
Exception in thread “main” com.aspose.cells.CellsException: Map size (0) must be >= 1
at com.aspose.cells.Ax.a(Unknown Source)
at com.aspose.cells.Workbook.a(Unknown Source)
at com.aspose.cells.Workbook.save(Unknown Source)
at AsposeExcelToPdf.main(AsposeExcelToPdf.java:37)

I have attached a sample program which I’m using to do the conversion to isolate problems that might be related to integration with our application. I’ve also attached a sample file causing the problem, we have several other files giving the same error.
