The Vuex MutationAction decorator cannot be assigned to a TypedPropertyDescriptor

I am a beginner in Typescript and apologize in advance if this is a rookie mistake.

I am struggling to resolve this TS error:

@Module({ namespaced: true, name: "Admin" })
class Admin extends VuexModule {
  public adminUserList: UserList = [];

  @MutationAction({ mutate: ["adminUserList"] })
  async getAdminUserList(): Promise<Record<string, UserList>> {
    const req = (await Utils.async({
      data: adminUserList,
    })) as Record<string, UserList>;

    return {
      adminUserList: req.data as UserList,
    };
  }
}

Answer №1

After some consideration, I realized that all I needed to do was adjust the return type of the action.

@Module({ namespaced: true, name: "Admin" })
class Admin extends VuexModule {
  public adminUserList: UserList = [];

  @MutationAction({ mutate: ["adminUserList"] })
  async getAdminUserList(): Promise<Record<"adminUserList", UserList>> {
    const req = (await Utils.async({
      data: adminUserList,
    })) as Record<string, UserList>;

    return {
      adminUserList: req.data as UserList,
    };
  }
}
