Ion push failing with error message about (missing?, unreadable?) maven artifact ion-1.0.47.jar

Question

Attempting to push an ion and get an error about not finding (or unable to read) ion-1.0.47.jar. I tried some troubleshooting and I don't think it is a permissions issue, because I am able to use the aws cli and copy ion-0.9.7.jar. So why is 1.0.47 not working?

deps.edn:

{:mvn/repos {"datomic-cloud" {:url "s3://datomic-releases-1fc2183a/maven/releases"}}

 :aliases {
           :ion-dev {:deps {com.datomic/ion-dev {:mvn/version "1.0.352"}
                            com.datomic/client-cloud {:mvn/version "1.0.131"}
                            com.datomic/ion {:mvn/version "1.0.71"}}
                     :main-opts ["-m" "datomic.ion.dev"]}}}

command I'm trying to run:

clojure -M:ion-dev '{:op :push :creds-profile "byt-wrought-test" :region "us-west-2"}'

error:

Based on some conversations I found on slack and datomic dev forum, I tried this as a troubleshooting step:

aws --profile byt-wrangle-test s3 cp s3://datomic-releases-1fc2183a/maven/releases/com/datomic/ion/0.9.7/ion-0.9.7.jar .

download: s3://datomic-releases-1fc2183a/maven/releases/com/datomic/ion/0.9.7/ion-0.9.7.jar to ./ion-0.9.7.jar

and that works. But the same attempt with 1.0.47 does not:

aws --profile byt-wrangle-test s3 cp s3://datomic-releases-1fc2183a/maven/releases/com/datomic/ion/1.0.47/ion-1.0.47.jar .
