|Failed exports on empty preparations||When using the Export button in a dataset that you
just opened from the dataset list, without applying any preparation function,
exports will fail regardless of the output configuration.
As a workaround, apply at least one preparation step to the dataset in order to create a preparation and export it to the format of your choice.
