Getting no handler accepted

Hi

I'm a haskell beginner and I'm getting the error not found "No handler accepted "/users" when trying to access the url localhost:8081/users. The root, only localhost:8081/ shows some graphs but the /users endpoint gives me not found.

The UserAPI:

type UserAPI = "users" :> Get '[JSON] [Entity User] :<|> "users" :> Capture "name" Text :> Get '[JSON] (Entity User) :<|> "users" :> ReqBody '[JSON] User :> Post '[JSON] Int64 :<|> "metrics" :> Get '[JSON] (HashMap Text Int64)

The server:

userServer :: MonadIO m => ServerT UserAPI (AppT m)
userServer = allUsers :<|> singleUser :<|> createUser :<|> waiMetrics

allUsers :: MonadIO m => AppT m [Entity User]
allUsers = do
    increment "allUsers"
    logDebugNS "web" "allUsers"
    runDb (selectList [] [])`

You have to set the content-type to application/json. If you open with your browser, it will ask for HTML or plaintext. Try opening with your browser just localhost:8081/ and using the primitive UI there?
