When I saving the new visualization(called "New Visualization123") in kibana, I encountered the following error.
Not only in Visualization, when I created the Index patterns in management, I also encountered this error.
I checked selasticsearch and kibana's logs and found no error.
What's wrong ?
(I have saved almost 165 objects in the kibana,Is it possible that there are too many saved objects.)
Thanks a lot for your assistance !
