Deprecation warning: The “sourceId” asset query param has been deprecated.

Craft gives a warning in the 'Deprecation Warnings' tab.

Deprecation warning: The “sourceId” asset query param has been deprecated. Use “volumeId” instead.

I tried to just replace sourceId with volumeId when fetching assets, but that doesn't work. Ideally I could just fetch assets from a given volume based on the handle for the volume, but can't figure out a way to do this either.

How should this be solved?
