From your stacktrace it looks like the underlying issue is caused by the fact that the Spreadsheet::WriteExcel::Chart::* modules are dynamically loaded via a factory method. This probably means that the Cava code analyser doesn't detect that they are required and doesn't load them in the package.

A solution would probably be to explicitly include them in the your root program using "use": 

    ...
    use Spreadsheet::WriteExcel;
    use Spreadsheet::WriteExcel::Chart::External;
    ...
