-------------------------------------
Hi [~freds],
the URL you posted is not valid.
See for valid {{$count}} URLs the [OData V4
specification|http://docs.oasis-open.org/odata/odata/v4.0/errata02/os/complete/part2-url-conventions/odata-v4.0-errata02-os-part2-url-conventions-complete.html#_Toc405999462].
However you have the possibility to get the count as {{odata.count}} value in
the response by adding {{$count=true}} (e.g.
http://localhost:8080/odata-server-sample/cars.svc/Cars/?$count=true&$filter=Price%20eq%201000
).
Kind regards,
Michael
PS: You can also try with another OData Sample Service:
http://services.odata.org/V4/(S(qvx0f4gpdzvegedocxrdpzh2))/TripPinServiceRW/People/$count?$filter=FirstName%20eq%20%27Scott%27
and a valid *odata.count* value:
http://services.odata.org/V4/(S(qvx0f4gpdzvegedocxrdpzh2))/TripPinServiceRW/People/?$count=true&$filter=FirstName%20eq%20%27Scott%27
