Reference service OData lambda queries don't work

Hello,

I’m trying to use OData reference service with OData ‘any’ function and getting errors consistently.

These examples

http://services.odata.org/TripPinRESTierService/(S(3mslpb2bc0k5ufk24olpghzx))/People?$filter=AddressInfo/any(o:o/Address eq '87 Polk St. Suite 5')
http://services.odata.org/TripPinRESTierService/(S(3mslpb2bc0k5ufk24olpghzx))/People?$filter=Emails/any(o:o eq 'Russell@contoso.com')

produce

{
    "error": {
        "code": "",
        "message": "Value cannot be null.\r\nParameter name: source"
    }
}

I cannot check if the collection itself is null

http://services.odata.org/TripPinRESTierService/(S(3mslpb2bc0k5ufk24olpghzx))/People?$filter=Emails ne null

{
    "error": {
        "code": "",
        "message": "The operand for a binary operator 'NotEqual' is not a single value. Binary operators require both operands to be single values."
    }
}

If I use the lamda query from the collection
http://services.odata.org/TripPinRESTierService/(S(3mslpb2bc0k5ufk24olpghzx))/Me/Friends?$filter=Friends/any(f:f/FirstName eq 'Scott')

it doesn’t return an error, however it doesn’t seem to work correctly since none of the results have string “Scott” in them

Start by reproducing the three reported queries against the TripPinRESTierService URLs, especially the collection lambda filters and the Emails null comparison. Trace the reference service's OData lambda-query handling; done means the examples return correct filtered results or clear, valid errors instead of null-source failures.
