generateKeywordHistoricalMetrics Not returning aggregateMetricResults

[teambs]

For the end point 

https://googleads.googleapis.com/v13/customers/${customerclientid}:generateKeywordHistoricalMetrics

we are seeing only results object in response, we are not getting 

aggregateMetricResults for devices

As aggregateMetricTypess is mentioned it should return aggregateMetricResults

Are there any restrictions?

can we get devices data for 5,000 keywords at a time,  or only one keyword at a time?

let link=`https://googleads.googleapis.com/v13/customers/${customerclientid}:generateKeywordHistoricalMetrics`;

//googleads.googleapis.com

const fetchresult=await fetch(link,{

method: 'POST',

body:JSON.stringify({

// "keywords": keywordstobeplanned,

"keywords": ["sharad pawar"],

// "includeAdultKeywords": true,

"geoTargetConstants": [

"geoTargetConstants/2356","geoTargetConstants/2826","geoTargetConstants/2036"

],

"keywordPlanNetwork": 'GOOGLE_SEARCH',

"aggregateMetrics":

{

"aggregateMetricTypes":["DEVICE"]

},

"language": "languageConstants/1000"

}),

headers:{

"Content-Type": 'application/json',

"Authorization": `Bearer ${access_token}`,

"developer-token": `xxxxxxxxxxxxxxxxx`,

"login-customer-id": customerid

}

});

var finalresult=await fetchresult.json();
