Coinbase Advanced Trading API下单提示‘account is not available’错误求助

开发加密货币交易机器人时，调用Coinbase Advanced Trading API的获取/列出账户接口可正常返回数据，但调用下单接口时始终返回400错误，提示account is not available。

代码示例 #

import requests
import json
import uuid

def place_order(symbol, side, amount, price=None):
    url = 'https://api.coinbase.com/api/v3/brokerage/orders'
    headers = {
        'Authorization': 'Bearer '+encryption_build.build_jwt(
            'POST api.coinbase.com/api/v3/brokerage/orders',
            api_key,
            api_secret),
        'Content-Type': 'application/json'
    }
    client_order_id = uuid.uuid4()
    try:
        # Order details
        order_data = {
          "client_order_id": str(client_order_id),
          "product_id": symbol,
          "side": side,
          "order_configuration": {
            "market_market_ioc": {
              "base_size": str(amount)
            }
          },
          "retail_portfolio_id": "41864a16-1fd4-50bb-a633-278d9c39f846"
        }
        res = requests.post(url=url, headers=headers, data=json.dumps(order_data))
        print(res.json())  # 补充打印响应便于调试
    except Exception as e:
        print(f"An error occurred: {e}")

place_order('BTC-USD',  'SELL', amount=0.01)

返回错误 #

{
    "error":"INVALID_ARGUMENT",
    "error_details":"account is not available",
    "message":"account is not available"
}

补充信息 #

• API密钥已配置查看/交易权限，List Accounts接口可正常返回我的Coinbase账户，包含活跃的BTC账户和CAD法定货币账户。
• 无论是否指定retail_portfolio_id，或是用Postman直接测试，都会返回相同错误。

期望结果：调用下单接口后返回200状态码，订单在Coinbase端处于待处理或已成交状态。网上相关资料极少，求解决思路。
