The error was misleading.  The userSessionPersister needed to be mongo instead of jpa.  The documentation said: "

However in all cases, you will need to updatestandalone/configuration/keycloak-server.json and add userSessionPersister like this:"


"userSessionPersister": {
    "provider": "jpa"
},

I have this in my keycloak-server.json file:

"connectionsMongo": {

            "host": "xx.xx.xx.xx",
