HistoricalChainResolution - Returns Invalid RICs as "Valid"

I am trying to search individual RICs from a Chain RIC by using HistoricalChainResolution.

Then found that retuned list of RICs actually contains Invalid RICs as well ( while status indicates "Valid" )

For instance, Below request will return bunch of individual RICs.

Request :

URL : {{protocol}}{{host}}{{api}}Search/HistoricalChainResolution

Body:

{

"Request": {

"ChainRics": [

"0#CDSBNKJPR="

],

"Range": {

"Start": "2022-05-01T00:00:00.000Z",

"End": "2022-05-16T00:00:00.000Z"

}

}

}

Return

{

"@odata.context": "https://selectapi.datascope.refinitiv.com/RestApi/v1/$metadata#Collection(DataScope.Select.Api.Search.HistoricalChainInstrument)",

"value": [

{

"Identifier": "0#CDSBNKJPR=",

"IdentifierType": "ChainRIC",

"Source": "",

"Key": "VjF8MHgzMDAwMDAwMDAwMDAwMDAwfDB4MzAwMDAwMDAwMDAwMDAwMHx8fHx8fHwwI0NEU0JOS0pQUj18",

"Description": "Historical Chain",

"InstrumentType": "Unknown",

"Status": "Valid",

"Constituents": [

{

"Identifier": "AOZR10YUSAC=R",

"IdentifierType": "Ric",

"Source": "",

"Key": "VjF8MHgzMDAwMDAwMDAwMDAwMDAwfDB4MzAwMDAwMDAwMDAwMDAwMHx8fHx8fHxBT1pSMTBZVVNBQz1SfA",

"Description": "Historical Instrument",

"InstrumentType": "Unknown",

"Status": "Valid",

"DomainCode": "6"

},

...... ( Bunch of RICs will follow, but some are non existing RICs as well as valid RICs )

Actually , In above example, one of retuned RIC "AOZR10YUSAC=R" is actually no longer exist ( so invalid RIC ) , but somehow those invalid RICs are retuned with the valid RICs , "Status" of those RICs indicated as "Valid" as well as other existing ( valid ) RICs.

Is there anyway to exclude such invalid RICs from the returned RICs??

Thank you
