• I have a collection which have document like these:

{ "_id" : ObjectId("599c05310252805c00f4f03d"), "facets" : [ { "id" : "culture", "values" : [ "hindu" ] }, { "id" : "occasion", "values" : [ "pre_wedding_shoot" ] }, { "id" : "photo_bucket", "values" : [ "wedding_photography" ] }, { "id" : "style_of_photography", "values" : [ "traditional" ] } ] }

• Every document has a field facets which is an array of object. Each object in the array has two fields: id: <string> and values: [<string>]. My model file is attached with this ticket:
  seo_media_details.txt

• Now when I try to query the REST API build with this plugin with following code

requestPromise({ uri: localhost:3000/api/v1/seo_media_details, qs: { query: JSON.stringify({ 'facets': { '$all': [ { 'id': "xxx", 'values': ['a', 'b', 'c'] } ] } }, resolveWithFullResponse: true }).then( ... )

• but if change the value of values from an array to a single item. It works.

requestPromise({ uri: localhost:3000/api/v1/seo_media_details, qs: { query: JSON.stringify({ 'facets': { '$all': [ { 'id': "xxx", 'values': 'a'} ] } }, resolveWithFullResponse: true }).then( ... )

, it doesn't work, I get following error.
