RxSwift URLSession request is disposed - swift

Question

I'm learning to use RxSwift and I'm stuck using this simple code. My intention is to take an APIRequest type, as simple as this:
public protocol APIRequest: Encodable {
associatedtype Response: Decodable
var path: String { get }
}
Pass it to the API Client and finally return an Observable of type T.Response, however, I'm constantly seeing cancelled status in my console:
2019-07-01 10:46:04.847: test api request -> subscribed
2019-07-01 10:46:04.855: test api request -> isDisposed
This is my APIClient's code:
func send<T: APIRequest>(_ request: T) -> Observable<T.Response> {
guard let fullURL = endpoint(for: request) else {
return Observable.error(APIError.invalidBaseURL)
}
return Observable<T.Response>.create { observer in
let request = URLRequest(url: fullURL)
let response = URLSession.shared.rx.response(request: request)
.debug("test api request")
return response.subscribe(onNext: { response, data in
if 200..<300 ~= response.statusCode {
guard let responseItems = try? self.jsonDecoder.decode(T.Response.self, from: data) else {
return observer.onError(APIError.decodingFailed)
}
observer.onNext(responseItems)
observer.onCompleted()
}
}, onError: { error in
observer.onError(APIError.other(error))
}, onCompleted: nil,
onDisposed: nil)
}
}
I've been trying to get the results printed to the console with:
apiClient.send(countriesRequest)
.subscribe(onNext: {
print("Success", $0)
}, onError: {
print("Error: ", $0)
}, onCompleted: {
print("Completed!")
})
.disposed(by: disposeBag)
What am I doing wrong and why?

I've tried to recreate your code, and it seem working fine on my device:
func send<T>(_ request: T) -> Observable<Data> {
let request = URLRequest(url: URL(string: "sdf")!)
return Observable.create { obs in
URLSession.shared.rx.response(request: request).debug("r").subscribe(
onNext: { response in
return obs.onNext(response.data)
},
onError: {error in
obs.onError(error)
})
}
}
I'm subscribing to it, and it produces an error
send("qwe").subscribe(
onNext: { ev in
print(ev)
}, onError: { error in
print(error)
}).disposed(by: disposeBag)
