why does only the thumbnail function in the chart work? The dashboard does not appear.

I installed superset with helpm. Added thumbnail function. By the way, why does only the thumbnail function in the chart work? The dashboard does not appear.

If you look at the superset worker log below, it is as follows.
What's interesting is that the charts come out well.

Why do dashboards have timeouts?
Why doesn’t the chart time out?

Hi @dragonball-wooboo , there was a regression on master branch that caused dashboard thumbnails to fail. This was fixed by #23003 which was recently merged. Closing as fixed.
