Fedora package not found when building on docker hub, works building locally

Getting the following error installing the ‘fd-find’ package on a fedora 30 image based container:

+ dnf install -y fd-find
Last metadata expiration check: 0:07:34 ago on Sat May 4 15:48:53 2019.
No match for argument: fd-find
Error: Unable to find a match

This works if I build the docker image locally - any reason why it would fail consistently when built on docker hub?
