反应格子链接错误加载格子空

如何解决反应格子链接错误加载格子空

我终其一生都无法弄清楚这里出了什么问题。我检查了一些问题，似乎错误加载格子空值在过去一直是一个问题。我能够成功创建链接令牌并在传递到 PlaidLink 之前显示它。 PlaidLink 按钮保持禁用状态，在控制台中我收到错误加载 plaid null。我错过了什么？这是 Plaid 文档的链接。 https://github.com/plaid/react-plaid-link

我正在使用“react-plaid-link”：“^3.2.0”

这是我的代码。

import React,{ useCallback,useState,FunctionComponent,useEffect } from "react";
import { usePlaidLink,PlaidLinkOptions,PlaidLinkOnSuccess } from "react-plaid-link";
// @ts-ignore
//import { PlaidLinkOnSuccess } from "react-plaid-link/src/types/index.ts";



interface Props {
  token: string;
}

const PlaidLink: FunctionComponent<Props> = ({ token }) => {


  const onSuccess = useCallback<PlaidLinkOnSuccess>(
(public_token: any,metadata: any) => {
  // send public_token to server
  const setToken = async () => {
    console.log("token sending to server for exchange")
    const response = await fetch("/api/set_access_token",{
      method: "POST",headers: {
        "Content-Type": "application/x-www-form-urlencoded;charset=UTF-8",},body: `public_token=${public_token}`,});
  };
},[]
  );

  const config: PlaidLinkOptions = {
token,onSuccess,// onExit
// onEvent
  };



  const { open,ready,error } = usePlaidLink(config);

  return (
<div>
  <p>{token}</p>
  <button
    onClick={() => open()}
    disabled={!ready}
  >
    Connect a bank account
  </button>
</div>
  );
};


const PrePlaid: FunctionComponent = () => {
  const [token,setToken] = useState<string | null>(null);

  // generate a link_token
  React.useEffect(() => {
async function createLinkToken() {
  let response = await fetch("/api/create_link_token");
  const { link_token } = await response.json();
  console.log("this is the link token" + link_token);
  setToken(link_token);
}
console.log("this should happen first")
createLinkToken();
  },[]);

  // only initialize Link once our token exists
  return token === null ? (
// insert your loading animation here
<div className="loader"></div>
  ) : (
  <PlaidLink token={token} />
  );
    }

export default PrePlaid;

解决方法

在 index.html 中缺少脚本标记
