In order to deal with the Chrome Samesite cookies issue I have just upgraded ES and Kibana from 6.7 to 6.8 and that went fine. I then went to upgrade ES to 7.10 and now I am getting The below error message. I had followed the upgrade assistant and it said everything was good. I'm not sure what is wrong at this point. I only have one cluster so I thought this should be a fairly straightforward process.
