Argument of type 'string' is not assignable to parameter of type 'never'.

When using setState in a provider I get this error since the new update, is there any way to fix it ? Argument of type 'string' is not assignable to parameter of type 'never'.

What is the type of StoreState?

/**
 * Store type
 */
type StoreState = {
  readonly toolMode: ToolMode
  readonly cursor: string
  readonly drawColor: string
  readonly drawWidth: number

type ContextState = [
  state: StoreState,
  actions: {
    /**

I don't seem to be able to reproduce the issue 🤔 https://playground.solidjs.com/anonymous/6b9a5fd8-a0ec-42c0-a49c-a4c67f90c525

huh so it might come from my ts config ? what version of solid is the playground in ?

D0ZOP•2y ago

here is the declaration of setState for version 1.6.9

iirc it was changed so that readonly properties aren't settable by setStore since those are most commonly a result of using getter properties which cause a runtime error if you try to set them

oh alright removing readonly worked, thanku 😄
