python 请求：ValueError：连接超时值是 <object object at 0x7c6b5e484a80>，但它必须是 int、float 或 None

Question

我将

google-cloud-bigquery

从版本

3.11.4

更新为

3.12.0

。 requests 和 urllib3 已绑定。

requests==2.31.0
requests-futures==1.0.1
requests_pkcs12==1.21
urllib3==1.26.18

有时我会收到此错误，但不明白为什么：

    raise ValueError(
ValueError: Timeout value connect was <object object at 0x7c6b5e484a80>, but it must be an int, float or None.

我在其他问题上看到这是因为我需要将 urllib3 降级到小于 2 的版本，但这已经是我的情况了。

该错误表明正在传递无效的超时值。确保您的请求中的超时参数设置正确。例如：

import requests

response = requests.get('https://example.com', timeout=(5, 27))

检查代码或依赖项的任何部分是否不正确地修改了超时值。
