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.
