Current behaviour

Current Behavior

• When selecting multiple notes for PDF export, if the user clicks "Export" > "PDF" and then cancels the operation, an error dialog is displayed.
• This error occurs because the code expects a string from bridge().showOpenDialog(), but receives an empty array instead, leading to a failure in processing the cancellation.

Expected behaviour

Expected Behavior

• When the user cancels the bulk PDF export by clicking "Cancel," no error dialog should be shown.
• The application should correctly handle the return value of bridge().showOpenDialog(), accounting for the possibility of receiving an empty array.
• If the user proceeds with the export, the application should correctly export the selected notes to the specified directory without any errors.
