I’m trying to connect Redash to my AWS Athena. I have succeeded before. However, this time when I set up all the configurations, passed the connection test, a weird situation happened in the creating new query scene. In the scene, the area on the left side of the queries, which lists all my tables, disappeared. However, for my old data source, the list still shows up. But it contains some old tables which I’ve already deleted in Athena. So I guess there is some connection errors between Athena and Redash. Anyone have any idea?

PS: I used my root account AWS keys, so there shouldn’t be any permission problems.
