Hi there,

We've encountered an issue with the Gantt MspExport where an error surfaces if the export is triggered on an empty project.

This is reproducible in the msprojectexport example https://bryntum.com/products/gantt/examples/msprojectexport/ when removing the project.load() call and clicking the export button.

Uncaught TypeError: Cannot read properties of undefined (reading 'internalId')

Please could this be raised as a bug?

Thanks,
