I have problem with forwardRef in Typescript in ReactJS.
My goal is to wrap bootstrap FormControl and provide some simple logic for now on it then build on it. I know that FormControl forward its reference to the input element.
Now how can I forward a reference in my component to this reference that FormControl is forwarding. My code now looks like that:
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}
/>
);
}
);
At the line with ref={ref} I'm getting error:
No overload matches this call.
Overload 1 of 2, '(props: Readonly<ReplaceProps<"input", BsPrefixProps<"input"> & FormControlProps>>): FormControl<"input">', gave the following error.

I just can't figure out based on error message what is wrong here. It is too complicated for me. Can somebody help in this example?
