nimforum mirror - "invalid type ... in this context" error

I have this in the main module:

import ./elm


type
    State = object
        elmProgram: elm.Program
        portToElm: elm.SubPort[portMessages.Incoming]


# Error is with this function
proc newState(
    elmProgram: elm.Program,
): State =
    return State(
        elmProgram: elmProgram,
        portToElm: elmProgram.getSubPort("rawSubscribe"),
    )

The asshole compiler told me:


Error: invalid type: 'SubPort[SubPort.T]' in this context: 'proc (elmProgram: Program): State' for proc

This is the elm module:

type
    Program* {.importjs.} = ref object of JsRoot
    SubPort*[T: JsRoot] {.importjs.} = ref object of JsRoot


# Get a reference to a Sub port (to Elm)
proc getSubPort*[T: JsRoot](
    program: Program,
    name: cstring,
): SubPort[T] {.importjs: "#.ports[#]".}
