我在 ReactJS 的 Typescript 中遇到 forwardRef 问题。

我的目标是包装引导程序 FormControl 并在其上提供一些简单的逻辑，然后在其上构建。我知道 FormControl 将其引用转发给输入元素。

现在，如何将组件中的引用转发到 FormControl 正在转发的引用。我的代码现在看起来像这样：

import React from "react";
import { Form } from 'react-bootstrap';

export type FormSimpleTextProps = {
    name: string;
    placeholder: string;
    value: string;
    updated: boolean;
    editable: boolean;
    onChange: (name: string, newValue: string) => void;
};

export const FormSimpleText = React.forwardRef(
    (props: FormSimpleTextProps, ref: React.Ref<HTMLInputElement>) => {

        const onChangeHandler = (e: React.ChangeEvent<HTMLInputElement>) => {
            console.log(e);
        }

        return (
            <Form.Control

               ref={ref}
                name={props.name}
                value={props.value}
                onChange={onChangeHandler}
                className={props.updated ? "selected" : ""}
                plaintext={!props.editable}
                readOnly={!props.editable}
                required
                type="text"
                placeholder={props.placeholder}
            />
        );
    }
);

在 ref={ref} 行我收到错误：

No overload matches this call.
  Overload 1 of 2, '(props: Readonly<ReplaceProps<"input", BsPrefixProps<"input"> & FormControlProps>>): FormControl<"input">', gave the following error.

    20 |         return (
    21 |             <Form.Control
  > 22 |                 ref={ref}
       |                 ^
    23 |                 name={props.name}
    24 |                 value={props.value}
    25 |                 onChange={onChangeHandler}

我只是无法根据错误消息弄清楚这里有什么问题。这对我来说太复杂了。有人可以在这个例子中提供帮助吗？
