Adding non existent and not required keystore fails

We are in a case where a CLI script is executed in an embedded server. They keystore added doesn't exist locally when the script is run. The operation is:

/subsystem=elytron/key-store=keystore:add(required=false, path="/etc/foo/keystore.jks", credential-reference={clear-text=${keystore.password}})

Error:

"failure-description" => {"WFLYCTL0080: Failed services" => {"org.wildfly.security.key-store.keystore" => "WFLYELY00004: Unable to start the service.
[ERROR] Caused by: org.jboss.msc.service.StartException in anonymous service: WFLYELY00022: KeyStore file '/etc/wf-secrets/keystore.jks' does not exist and required."}},
