Error while run Elasticsearch query

[michalbarilan]

Hi, I'm trying to create a dashboard with Redash.
The connection with Jira worked as expected and I got the results.
Connection to Elasticsearch tested successfully, but when I tried to run a query I got 'Error running query: Expecting value: line 1 column 1 (char 0)', and when refreshed the 'New Query' page with elastic as data source I got 'Schema refresh failed. Please try again later.' error

I run it on Docker on my local machine.
I would appreciate your help. Thanks!
