【问题描述】：
我刚刚开始使用格子呢。我已经在本地设置了快速启动应用程序，它在沙盒模式下运行良好。链接面板加载正常，我可以使用沙盒凭据登录机构。
我的.env 文件如下所示：
PLAID_CLIENT_ID=xxxxxxxx
PLAID_SECRET=xxxxxxxx
PLAID_ENV=sandbox
PLAID_PRODUCTS=transactions
PLAID_COUNTRY_CODES=US,CA
PLAID_REDIRECT_URI=http://localhost:3000
我现在想检查 Plaid 是否可以与一些特定的真实/实时机构合作，因此我正在尝试更新我的快速入门应用以在开发模式下工作。为此，我只需将 PLAID_SECRET 更新为我的开发密钥，并将 PLAID_ENV 更新为“开发”。
当我现在启动应用程序时，开始页面不再显示“启动链接”按钮，而是显示：
日志表明问题发生在 POST /api/create_link_token 调用上。如果我从该路由函数中删除错误处理，日志会显示问题：

plaid.exceptions.ApiException: (400)
Reason: Bad Request
HTTP response headers: HTTPHeaderDict({'Server': 'nginx', 'Date': 'Sun, 16 May 2021 18:22:05 GMT', 'Content-Type': 'application/json; charset=utf-8', 'Content-Length': '301', 'Connection': 'keep-alive'})
HTTP response body: {
"display_message": null,
"documentation_url": "https://plaid.com/docs/?ref=error#invalid-input-errors",

"error_message": "invalid client_id or secret provided",
"error_type": "INVALID_INPUT",
"request_id": "EbCTgZkFdeYQQ8r",
"suggested_action": null
}
所以这表明我使用了错误的客户端 ID 或密码，但我不明白。客户端 ID 应该没问题（它在沙盒模式下工作），秘密绝对是我的开发模式的秘密（我什至尝试过生成一个新的但没有区别）。我错过了什么吗？
最后，如果我使用 Postman POST 到 https://development.plaid.com/link/token/create 创建一个链接令牌，使用相同的客户端 ID 和“开发”秘密，它似乎工作正常（即我得到一个 200 响应和全新的链接令牌） .
非常感谢任何帮助！
