Hi, I’m using Grafana (currently running 6.5.2), and am having difficulty writing queries against our Elasticsearch 7 deployment on my virtual server. The data source is configured correctly: the “Save and test” button gives me a green tick. However, when I try to query the data source from a Grafana widget, including in the Explore view, I receive an error saying “Failed to create query”. This seems to be the case for any query I write against the data source in Grafana: all the Elastic-backed widgets are blank right now. An example failed query from the error report is:
failed to create query: { “bool” : { “filter” : [ { “range” : { “@timestamp” : { “from” : “1577405631981”, “to” : “1577426420079”, “include_lower” : true, “include_upper” : true, “format” : “epoch_millis”, “boost” : 1.0 } } }, { “query_string” : { “query” : “*”, “fields” : [ ], “type” : “best_fields”, “default_operator” : “or”, “max_determinized_states” : 10000, “enable_position_increments” : true, “fuzziness” : “AUTO”, “fuzzy_prefix_length” : 0, “fuzzy_max_expansions” : 50, “phrase_slop” : 0, “analyze_wildcard” : true, “escape” : false, “auto_generate_synonyms_phrase_query” : true, “fuzzy_transpositions” : true, “boost” : 1.0 } } ], “adjust_pure_negative” : true, “boost” : 1.0 } }
I don’t know what is the problem?
Please help me to find out the solution.
