I am trying to locate Comex Copper Option information (Ric root is HG). In Datascope, I get the following after searching broadly...

but when I try to follow the tutorial example, and submit the following request, it returns nothing..
requestUrl = "https://hosted.datascopeapi.reuters.com/RestApi/v1/Search/FuturesAndOptionsSearch"
requestHeaders={
"Prefer":"respond-async",
"Content-Type":"application/json",
"Authorization": "token " + token
}
requestBody={
"SearchRequest": {
"AssetStatus": "Active",
"FileCodes": None,
"CurrencyCodes": None,
"ExchangeCodes": None,
"FuturesAndOptionsType": "Options",
"IdentifierType": "Ric",
"Identifier": "HG*",
"PreferredIdentifierType": "Ric",
"UnderlyingRic": "HG"
}
}
I have also supplied the exact identifer per the Datascope output, but also nothing.. I'm at a loss...
Thanks for any help.
