我在我的项目（React、TS、Mobx）中添加了 onChange 方法，但出现错误： Argument of type '{ [x: number]: any; }' is not assignable to parameter of type

我是 TypeScript 的新手，不知道为什么会这样。可能是什么问题？

(parameter) event: {
    target: {
        name: any;
        value: any;
    };
}

'{ [x: number]: any; 类型的参数 }' 不可分配给类型为 'IAddPlayerFormState | 的参数 ((prevState: Readonly, props: Readonly) => IAddPlayerFormState | Pick | null) | 选择<...> | 空值'。

import React, { Component } from 'react';
import ViewStore from '../../../store/ViewStore';
import { TextField } from './../../../utils';

interface IAddPlayerFormProps {
  viewStore?: ViewStore; // Optional ViewStore
}

interface IAddPlayerFormState {
  playerName: string;
  isDisabled: boolean;
}

class AddPlayerForm extends Component<IAddPlayerFormProps, IAddPlayerFormState> {
  constructor(props: Readonly<IAddPlayerFormProps>) {
    super(props);

    this.state = {
      isDisabled: false,
      playerName: '',
    };
  }

  public onChange(event: { target: { name: any; value: any; }; }) {
    this.setState({ [event.target.name]: event.target.value });
    console.log('On Change!');
  }

  public handleSubmit = () => {
    console.log('On submit!');
  }

  public render() {
    const { isDisabled } = this.state;

    return (
      <form onSubmit={this.handleSubmit}>
        <TextField
          type="text"
          name="name"
          value={name}
          placeholder="Add player"
          onChange={this.onChange}
          disabled={isDisabled}
        />

        <input type="submit" />
      </form>
    );
  }
}

export default AddPlayerForm;
