MongoDB bson.M query - mongodb

Question

I am trying to query using bison all JSON data in MongoDB with two fields but am getting null as result.
{
"allowedList": [
{
"List": [
{
"allow": {
"ss": 1,
},
"Information": [
{
"Id": "Id1"
}
]
}
]
}
]
}
I was able to filter all using the MongoDB at command line using
db.slicedb.find({"allowedList.List.allow.ss":1,"allowedList.List.Information.nsiId":"Id-Id21"})
but using
query := bson.M{"allowedList.List.allow": bson.M{"ss": sst}, "allowedList.List.Information": bson.M{"Id": Id}}
sst and Id are integer and string input to the query function
err := db.C(COLLECTION).Find(query).All(&specificSlices)
but is not working, am getting null even though there are json data that match the two field. Can someone help point out what was wrong with my query?
Server and database config
type SliceDataAccess struct {
Server string
Database string
}
var db *mgo.Database
const (
COLLECTION = "slicedb"
)
Establish a connection to database
func (m *SliceDataAccess) Connect() {
session, err := mgo.DialWithTimeout(m.Server, 20*time.Second)
if err != nil {
log.Fatal(err)
}
db = session.DB(m.Database)
}
Structs fields
type InstanceInfo struct {
ID string `json:"nfId" bson:"_id"`
AllowedList []AllowedNssai `json:"allowedList" bson:"allowedList"`
}
type AllowedNssai struct {
List []AllowedSnssai `json:"List,omitempty" bson:"List"`
...
}
type AllowedSnssai struct {
Allow *Snssai `json:"allow,omitempty" bson:"allow"`
Information []NsiInformation `json:"Information,omitempty" bson:"Information"`
}
type NsiInformation struct {
Id string `json:"Id" bson:"Id"`
}
type Snssai struct {
Ss int32 `json:"sst" bson:"ss"`
}
Query function defined
func (m *SliceDataAccess) FindAll(sst int32, nsiId string ([]InstanceInfo, error) {
var specificSlices []InstanceInfo
query := bson.M{"allowedList.List.allow": bson.M{"ss": sst}, "allowedList.List.Information": bson.M{"Id": nsiId}}
err := db.C(COLLECTION).Find(query).All(&specificSlices)
if err != nil {
return specificSlices, err
}
return specificSlices, nil
}
HTTP handler function for request and response
func AvailabilityGet(w http.ResponseWriter, r *http.Request)
var slice InstanceInfo
err := json.NewDecoder(r.Body).Decode(&slice)
if err != nil {
respondWithError(w, http.StatusBadRequest, "Object body not well decoded")
return
}
sst := slice.AllowedList[0].List[0].Allow.Sst
nsiId := slice.AllowedList[0].List[0].Information[0].Id
specificSlices, err := da.FindAll(sst, nsiId)
json.NewEncoder(w).Encode(specificSlices)
}
Attached is my the full go code i have done.

Answer 1

this worked
query := bson.M{"allowedNssaiList.allowedSnssaiList.allowedSnssai.sst": sst, "allowedNssaiList.allowedSnssaiList.nsiInformationList.nsiId": nsiId}
