我只是想plaid.io与Django. 为此，我正在使用示例。

<h1>Plaid Example Walkthrough</h1>
<p id="intro">
This is an example application that walks through integrating Plaid Link using the API to retrieve Auth and Transaction data.
</p>
<p id="steps">
Great - you just created an Item! The server was successfully able to exchange the public_token for an access_token.
Below are a few options - you can get account data, retrieve information about the Item itself, or pull transaction data.
</p>
</div>
<div id="container">
<p>
Click the button below to open a list of Institutions - after you select one,
you'll be guided through an authentication process. The public_token will be passed
back to the example server, which will then exchange it for an access_token and log it
to your console.

这与我的令牌完全相同。
但在终端中出现以下消息：
sandbox.plaid.com/link/client/get 加载资源失败：服务器响应状态为 400（错误请求）link.js:125 错误：检索公钥信息时出错。确保输入的密钥正确。如果错误仍然存在，请联系 support@plaid.com。在 link.js:125（匿名）@link.js:125 cdn.plaid.com/authenticate 加载资源失败：服务器响应状态为 403（禁止）
为什么我得到400 Bad Request Message？
