python - 间歇性'NoAuthHandlerFound' boto 错误 | django + kinesis 客户端

Question

即使在尝试解决方案之后：Boto3 间歇性 NoAuthHandlerFound 错误得到以下错误：

[Tue Aug 04 12:55:09.460312 2020] [wsgi:error] [pid 24727:tid 140597795952384]     creds = self._get_credentials_from_metadata(metadata)

[Tue Aug 04 12:55:09.460450 2020] [wsgi:error] [pid 24727:tid 140597795952384] You can set the 'metadata_service_num_attempts' in your boto config file to increase the number of times boto will attempt to retrieve credentials from the instance metadata service.

我AWS_METADATA_SERVICE_NUM_ATTEMPTS在机器上和 django settings.py 中都设置为 4。当我在代码中尝试手动重试时，它可以工作，但响应时间太长，并且请求排队并抛出 502、503 错误。

注意：身份验证是通过 IAM 角色进行的。
