filter AlertSummary

hi community, 

i want to filter the result of queryAlertSummary service by using aanother service that return query ( for example by thingName as a source and sourceProperty as a property: 

var result = {
"filters": {
"type": "And",
"filters": [
{
"type": "EQ",
"fieldName": "source",
"value": sourceThingName
},
{
"type": "EQ",
"fieldName": "sourceProperty",
"value": "mesure"
}
]
}
};

and i put this result as a query of queryAlertSummary service but I don't know what is the problem.

thank you in advance
