apache Ivy pulling artifact from AWS CodeArtifact

Question

I am working on an ant project, trying to download the artifact from AWS CodeArtifact using apache ivy. My ivysettings.xml is

<ivysettings>
    <properties file="${ivy.settings.dir}/ivysettings-file.properties"/>
    <settings defaultResolver="thechain"/>
    <credentials
        host="i****.d.codeartifact.us-west-2.amazonaws.com"
        username="aws"
        passwd="${CODEARTIFACT_AUTH_TOKEN}"/>
    <resolvers>
        <chain name="thechain">
            <ibiblio name="central" m2compatible="true" 
                root="https://repo1.maven.org/maven2/" />
            <ibiblio name="codeartifact" m2compatible="true" 
                root="https://i****.d.codeartifact.us-west-2.amazonaws.com/maven/****-repo/" checkconsistency="false"/>
        </chain>
    </resolvers>
</ivysettings>

It failed

In the credential, I skipped the realm and set the host name using the host part of the url. I wonder if that is correct? There is no documentation on the AWS Codeartifact about setting the host and the realm.

Any suggestion? Thanks
