When testing CLI setup for installs, I received this error, due to receiving an unexpected empty string:
ugs multiplay-hosting build installs 135745
Fetching installs...
Error calling GetBuildInstalls: Error converting value "" to type 'System.Guid'. Path '[0].ccd.bucketID', line 1, position 55.
But when I checked installs on another build, the data came back correctly and the CLI worked as intended.
My hunch is that it's because the functioning Build and the non-functioning Build have two different upload methods, the successful one being a Direct File Upload and the failing one being an Amazon S3 upload. They're functionally identical besides that, having been used on the same fleets and build configurations.
