Error "Missing kbn-version header" on query

I configured an elasticsearch datasource (test returns Index OK, field name OK)

But for any query in a graph panel for example, I receive this following error:
“statusCode”: 400,
“error”: “Bad Request”,
“message”: “Missing kbn-version header”

Is somebody know what is wrong?
Thanks in advance,

looks like you specified Kibana address and no the Elasticsearch address.

Thanks for the quick answer, I’m going to double check that one.
