RequestSyntax.send with generic response type

[pinguinson]

I'm trying to get rid of boilerplate methods like this one:

def fetchStuff: Future[List[Stuff]] = {
  val request = someClient.get("stuff").accept("application/json")
  request.send[List[Stuff]]
}

Tried this as well as replacing T in return type with List[T] but to no avail:

def fetch[T](endpoint: String): Future[List[T]] = {
  val request = someClient.get(endpoint).accept("application/json")
  request.send[List[T]]
}

Error:(30, 17) In order to decode a request to T, it must be known that a decoder exists to T from
all the content types that you Accept, which is currently String("application/json") :+: shapeless.CNil.
You may have forgotten to specify Accept types with the `accept(..)` method,
or you may be missing Decoder instances for some content types.
    request.send[T]

Is there any solution or should I just keep my boilerplate code?

Well, turned out I was dumb and forgot to add implicit DecodeAll instance:

def fetch[T](endpoint: String)
            (implicit decodeAll: DecodeAll[List[T], Coproduct.`"application/json"`.T]): Future[List[T]] = {
    val request = api.get(fetcher.endpoint).accept[Coproduct.`"application/json"`.T]
    request.send[List[T]]
}
