Query palette displays Unknown error

To correct this error, navigate to Media Manager > Edit > Preferences > Assets, and, under Checkout Location, either select “Application Directory” or specify the path to any other folder in “Other Location”.

Note: A best practice to follow is to have this folder located on the local system and not on a network volume.

Background: This error occurs when the Checkout location in the Media Manager Preferences is set incorrectly or the location no longer exists.
