we are using Kibana 7.3.0
I'm trying to download CSV output from a Discover query.
I saved the query, went to Share -> CSV Reports -> Generate CSV ... it spins for a few seconds and then returns an error that it can't generate the CSV.
When I navigate to Management -> Reporting, I see the failed report.
The full error message is
Unable to generate report
[index_closed_exception] closed, with { index_uuid="MshOUSAbTmiJnTYgxz5keA" & index="reindexed-v7-prod-metrics-2019.02.12" } :: {"path":"/prod-metrics-*/_search","query":{"scroll":"30s","size":500},"body":"{"stored_fields":["@timestamp","vendor","message"],"query":{"bool":{"filter":[{"multi_match":{"query":"dhcp","type":"best_fields","lenient":true}}],"must_not":,"should":,"must":[{"range":{"@timestamp":{"format":"strict_date_optional_time","gte":"2019-12-30T11:00:00.000Z","lte":"2019-12-30T11:30:00.000Z"}}}]}},"script_fields":{},"_source":{"excludes":,"includes":["@timestamp","vendor","message"]},"docvalue_fields":,"sort":[{"@timestamp":{"unmapped_type":"boolean","order":"desc"}}],"version":true}","statusCode":400,"response":"{"error":{"root_cause":[{"type":"index_closed_exception","reason":"closed","index_uuid":"MshOUSAbTmiJnTYgxz5keA","index":"reindexed-v7-prod-metrics-2019.02.12"}],"type":"index_closed_exception","reason":"closed","index_uuid":"MshOUSAbTmiJnTYgxz5keA","index":"reindexed-v7-prod-metrics-2019.02.12"},"status":400}"}
any help is appreciated.
