The Clojure CLI version 1.10.1.458 has an incompatibility with ion-dev. If you encounter an error:
{:deploy-status "ERROR",
:message "Could not find artifact
when performing an ion push, check your clojure CLI version (clojure -Sdescribe) If you’re using 1.10.1.458 you should temporarily revert to a previous version:
On Mac:
brew uninstall clojure
curl https://download.clojure.org/install/clojure-1.10.1.447.rb > clojure.rb
brew install clojure.rb
On Linux:
https://download.clojure.org/install/linux-install-1.10.1.447.sh
An updated version of the CLI will be released shortly to resolve this issue.
