Elasticsearch malformed query, expected [END_OBJECT] but found [FIELD_NAME] -

-



i'm using elasticsearch client doing search query using constant_score , aggregations it's throwing exception:

[parsing_exception] [constant_score] malformed query, expected [end_object] found [field_name]

this i'm creating query , calling search function:

fetchdata: function fetchfn(req, res, next) {     var model = new urlmodel();     util.log('fetching data es::');     var query = buildaggregateurl(req.reqdata);     // if (req.reqdata['domain']) {     //     var termfilter = { "term": { "domain": req.reqdata.domain } };     //     query.constant_score.filter.bool.must.push(termfilter);     // }     model.search({ query }, function (er, re) {         if (re) {             req.sendresult = re;         }         next(er);     });      function buildaggregateurl(opts) {         var query = {             constant_score: {                 filter: {                     bool: {                         must: [{                             "range": {                                 "timestamp": {                                     "gte": opts.starttime,                                     "lte": opts.endtime                                 }                             }                         }]                     }                 }             },             aggs: {                 success: {                     scripted_metric: {                         init_script: "params._agg.succ=0;",                         map_script: "if(doc.status.value=='success'){params._agg.succ+=1}",                         combine_script: "return params._agg.succ",                         reduce_script: "int sum=0;for (a in params._aggs){sum+=a}return sum"                     }                 },                 failure: {                     scripted_metric: {                         init_script: "params._agg.fail=0;",                         map_script: "if(doc.status.value=='failure'){params._agg.fail+=1}",                         combine_script: "return params._agg.fail",                         reduce_script: "int sum=0;for (a in params._aggs){sum+=a}return sum"                     }                 }             }         };         return query;     } }   , search function looks like:      es_model.prototype.search = function (opts, cb) {     var query = {         index: this.esconfig.index,         type: this.esconfig.type,         body: {query:opts.query}      };     console.log('query ===> ',query);     this.client.search(query, cb); }

i can't figure out problem syntax.i tried wrapping constant_score key withtin query doesn't seem work.

you're missing query element @ top level:

              {                 query: {                   constant_score: {                     filter: {                         bool: {                             must: [{                                 "range": {                                     "timestamp": {                                         "gte": opts.starttime,                                         "lte": opts.endtime                                     }                                 }                             }]                         }                     }                   }                 },                 aggs: {                     success: {                         scripted_metric: {                             init_script: "params._agg.succ=0;",                             map_script: "if(doc.status.value=='success'){params._agg.succ+=1}",                             combine_script: "return params._agg.succ",                             reduce_script: "int sum=0;for (a in params._aggs){sum+=a}return sum"                         }                     },                     failure: {                         scripted_metric: {                             init_script: "params._agg.fail=0;",                             map_script: "if(doc.status.value=='failure'){params._agg.fail+=1}",                             combine_script: "return params._agg.fail",                             reduce_script: "int sum=0;for (a in params._aggs){sum+=a}return sum"                         }                     }                 }             }

also note client code should this:

es_model.prototype.search = function (opts, cb) {      var query = {          index: this.esconfig.index,          type: this.esconfig.type,          body: opts.query     };      this.client.search(query, cb);  }

each commit git repo triggers build of jenkins pipeline. i want retrieve buildnumber of old build commit hash. how can that? i know information exists because can find in ui. some background why want this: when tags commit want create release (by tagging docker image). each build push image containing build number. want find out build number corresponds commit can find image want release. if understand question correctly, first need create git hook trigger new build. part covered in answer how react new tags in git hooks? ', though if using github, bitbucket or gitlab, there may other ways of going it. then when build initiated, there build number provided variable ' build_number ' ,in jenkins. if want include git tag name, can use in script, there seems fews ways: git parameter plugin git tag message plugin typically these plugins create environment variable can consumed scripts. not providing more concrete examples, since not aware of exact ...
