Elm: Chain Http.send and Http.get -

i'm (a beginner) having type issue trying chain http calls in elm application:

http.send ... `task.andthen` (\_ -> http.get ...) 

this because http.send return type task rawerror response, , http.get return type task error value.

any suggestion on how make them work together?

edit1:

maybe maperror solution?

edit2:

i'm not saying first call failed, i'm sure works. compiler doesn't validate code:

the right argument of `andthen` causing type mismatch.  135│     http.send http.defaultsettings config 136│>      `task.andthen` (\_ -> http.get (json.decode.list userjsondecoder) "http://localhost:3000/")  `andthen` expecting right argument a:      http.response -> task http.rawerror  right argument is:      http.response -> task http.error (list user) 

you need way map rawerror error , can use task.maperror suggested in first edit. 1 possibility be:

rawerrortoerror : http.rawerror -> http.error rawerrortoerror rawerror =   case rawerror of     http.rawtimeout -> http.timeout     http.rawnetworkerror -> http.networkerror  http.send http.defaultsettings config |> task.maperror rawerrortoerror `task.andthen` ...
