Shib IdP v5.1.3 - Upgrade issue with ArtifactResolutionService in metadata files

[Hall, Gerry]

I am upgrading from IdP v 4.3.3. to IdP v5.1.3 and installing v5.1.3 on top of v4.3.3.  Prior to the upgrade, v4.3.3 runs as expected.  I have updated all plugins, removed all deprecated warning messages, etc.  I am using amazon-corretto-17-aarch64-linux-jdk.tar.gz and apache-tomcat-10.1.2.   I run the update with no issues.

However, after the upgrade, when I start the IdP, I get errors like the below which point to lines like this
‘<md:ArtifactResolutionService Binding="urn:oasis:names:tc:SAML:2.0:bindings:SOAP" Location=https://osnode01.rwit.emory.edu/Shibboleth.sso/Artifact/SOAP index="1"/>’
in the service provider metadata files.

I am not sure that this is the best solution, but to test, I have removed the line from the metadata file.  When I then restart the IdP, the error disappears for that SP.  However, I have over 340 metadata files with the ‘ArtifactResolutionService’ line, and I would need to remove that line from all 340 metadata files.

My question is (1) is there a better way to resolve this error and (2.) what are the implications of removing ArtifactResolutionService in the SP SAML metadata file?  I have also read the doc here, https://shibboleth.atlassian.net/wiki/spaces/SP3/pages/2065334690/ArtifactResolutionService .
