Hi,
I am getting the following error on a single job:
> Job Validation Error: [parsing\_exception] [query\_string] unknown token [START\_OBJECT] after [query], with { line=1 & col=35 } :: {"path":"/usage-\*/\_search","query":{"size":0},"body":"{"query":{"query\_string":{"query":{"match":{"usage\_type.keyword":"IPASS"}}}},"aggs":{"earliest":{"min":{"field":"session\_start"}},"latest":{"max":{"field":"session\_start"}}}}","statusCode":400,"response":"{"error":{"root\_cause":[{"type":"parsing\_exception","reason":"[query\_string] unknown token [START\_OBJECT] after [query]","line":1,"col":35}],"type":"parsing\_exception","reason":"[query\_string] unknown token [START\_OBJECT] after [query]","line":1,"col":35},"status":400}"}
I want to filter on these sessions only and report on them.
The query entered is:
`{"query_string":{"query": {"match": {"usage_type.keyword": "IPASS"}}}}`
I then tried this: `{"query": {"match": {"usage_type.keyword": "IPASS"}}}` based on [ParsingException[[match] unknown token [START\_OBJECT] after [query]] - #3 by varun\_kumar2](https://discuss.elastic.co/t/parsingexception-match-unknown-token-start-object-after-query/103918/3) but that got me a new error:
> Job Validation Error: [parsing\_exception] no [query] registered for [query], with { line=1 & col=19 } :: {"patah":"/usage-\*/\_search","query":{"size":0},"body":"{"query":{"query":{"match":{"usage\_type.keyword":"IPASS"}}},"aggs":{"earliest":{"min":{"field":"session\_start"}},"latest":{"max":{"field":"session\_start"}}}}","statusCode":400,"response":"{"error":{"root\_cause":[{"type":"parsing\_exception","reason":"no [query] registered for [query]","line":1,"col":19}],"type":"parsing\_exception","reason":"no [query] registered for [query]","line":1,"col":19},"status":400}"}
I've tried this with different options and unable to get this to work.
Thanks in advance.
Wayne

Fixed it. I tried this (at least i thought I did) - value below fixed it:
`{"match": {"usage_type.keyword": "IPASS"}}}`
