Typescript+pinia: Problem about type of this

[YornQiu]

I created a store, it's like:

import { defineStore } from 'pinia';

export interface Person {
  name: string;
  age: number;
}

export default defineStore({
  id: 'useFactorFilters',
  state: (): Person => ({
    name: 'Jack',
    age: 18,
  }),
  actions: {
    setInfo<T extends keyof Person>(key: T, value: Person[T]) {
      this[key] = value;
    },
  },
});

Function setInfo is ok when it's used alone in other situations. But in pinia , i got a error:

I don't know how to handle it.
Appreciate if any suggestion!

And it only comes when the keys of Person are different types.

You can do

this.$state[key] = value

But I would recommend you not to create an action if it just sets a value:

store.name = newName
store.age = newAge
