I've been trying to create an Umbraco Package from the Packages tab within umbraco on V10 but got the below error when I've selected a Media folder to pull through all the images.

If I ignore selecting the media folder or even select individual media instead, everything seems to work accordingly.

Any idea?

Failed to create package Value cannot be null. (Parameter 'value')
