格子 webhook 必须是非空字符串 URL

Question

我正在使用 plaid-python 库调用 https://plaid.com/docs/api/tokens/#linktokencreate 端点。当我创建链接令牌请求时。

LinkTokenCreateRequest：

{'client_name': 'MYCLIENTNAME', 'country_codes': ['US'], 'language': 'en', 'products': ['auth', 'transactions'], 'user': {'client_user_id': 'XXXXXXXXXX'}, 'webhook': '/webhooks/091e07ab'}

格子的回应是：

{
"display_message": null,
"documentation_url": "https://plaid.com/docs/#create-link-token",
"error_code": "INVALID_FIELD",
"error_message": "webhook must be a non-empty string URL",
"error_type": "INVALID_REQUEST",
"request_id": "E************p",
"suggested_action": null
}

如果我省略了 webhook 参数，请求就会起作用。代码如下：

webhook_url = f"/webhooks/{user_hook_id}"
logger.info(f"webhook_url = {webhook_url}")
api_client = create_plaid_client()
client = plaid_api.PlaidApi(api_client)
token_request = LinkTokenCreateRequest( 
    products=[Products('auth'), Products('transactions')],
    webhook=webhook_url,
    client_name=client_name,
            country_codes=[CountryCode('US')],
            language='en',
            user=LinkTokenCreateRequestUser(
                client_user_id=user_hook_id
            )
        )
        logger.info(f"token_request = {token_request}")
        # create link token
        token_response = client.link_token_create(token_request)
        token = token_response['link_token']

我也尝试过使用完整的主机名和 uri，但都产生了相同的错误。请求有什么问题？

更新 1：

我再次运行测试，这是输出。这次我注意到 token_request 中的 webhook 的一件事是它的格式似乎不正确。我这样调用 LinkTokenCreateRequest：

token_request = LinkTokenCreateRequest( 
    products=[Products('auth'), Products('transactions')],
    webhook=webhook_url,
    client_name=client_name,
            country_codes=[CountryCode('US')],
            language='en',
            user=LinkTokenCreateRequestUser(
                client_user_id=user_hook_id
            )
        )

调用的输出如下。你可以看到 webhook 是用一个空字符串生成的，然后是我提供的 webhook。

webhook 参数需要在请求中包含整个 webhook 端点 URI，包括 https:// 部分。
