Aspose.cells: saving excel to pdf don't work on docker container

I’m trying to export an XLSx file to pdf in a docker container (I’ve tried to run it on mcr.microsoft.com/dotnet/core/runtime:3.1.1:apine3.10 and mcr.microsoft.com/dotnet/core/runtime:3.1.1:nanoserver-1809) but I’m facing this error

error:
Unhandled exception. Aspose.Cells.CellsException: The type initializer for '♠   ' threw an exception.
   at Aspose.Cells.Workbook.Save(String fileName, SaveOptions saveOptions)
   at Aspose.Cells.Workbook.Save(String fileName, SaveFormat saveFormat)

when trying to
workbook.Save("invoice.pdf", SaveFormat.Pdf);

works well on my Windows machine with Excel installed.

any clues?

@GersonDias,
Thank you for your query.

I have tested this scenario on Ubuntu 16.04 x64, in a docker container.
Here are my steps:

The docker I use is: microsoft/dotnet, install it first:
sudo docker pull microsoft/dotnet

Then, after running it, if I run this issue in this docker, I get the error:

Aspose.Cells.CellsException : The type initializer for ‘???’ threw an exception.
at Aspose.Cells.Workbook.Save(String fileName, SaveOptions saveOptions)

It seems to be the same error you also get.

Then I install libgdiplus:

apt-get update
apt-get install -y libgdiplus
cd /usr/lib && ln -s libgdiplus.so gdiplus.dll

And install libc6-dev:
apt-get install -y --no-install-recommends libc6-dev

After all these steps, the issue passed, and the pdf file created successfully.
Would you please check it and share the feedback?
