When I upgrade from 6.7 to 7, I am unable to create index pattern in Kibana.
Reference Video: https://youtu.be/ZYYt4fbGvao
In the world of 6.7, everything is working fine and I can create any index patterns in Kibana.
I tried to delete .kibana and let Kibana to create a new one, but the problem still exists.
I confirmed the creation of index pattern should be correct because I can query the index in .kibana index. The root cause would be unable to get index pattern by Kibana.
Can anyone help to troubleshoot this issue? Thanks.
