Unhandled exception during the execution: The type initializer for 'Gdip' threw an exception.

Fingers10.ExcelExport works fine on my windows machine, but when run in docker container, I have an exception which says

Unhandled exception during the execution: The type initializer for 'Gdip' threw an exception.

How do I resolve this ?

@nabeelmhd This is because you are running your app inside Linux container. You need to install few apks in your docker image build step to resolve this error. This is not packager related. Refer below link for solution or try googling on similar error. The fix should be added in docker image build.

Im also running the app in the linux container, working just fine in my w10 local env, but when i deploy my app to the test env, that excel download api wont work. returns cors error from react but from swagger returns Error: Internal Server Error. My .net version is 6. should i change my docker image too

@can123oz does this help? - https://stackoverflow.com/a/73055366/10851213

This is because of System.Drawing in non windows environment.

@can123oz I resolved by doing this in my docker file - https://stackoverflow.com/questions/60934639/install-fonts-in-linux-container-for-asp-net-core/76332225#76332225
