[BUG] 简洁阐述问题 / 问题1：IndexError: list index out of range 原因是代码尝试访问 d.choices[0].delta.content 时，choices 列表为空，导致索引超出范围。可能是 API 返回的 d 对象不符合预期结构。 问题2：AttributeError: 'IndexError' object has no attribute 'body' 在异常处理中，代码尝试访问 IndexError 异常的 body 属性，但 IndexError 对象没有这个属性，因此触发了二次异常。

@Yu-YuZhang 你好！我是Dosu，一个可以帮助你解决 bug、回答问题并成为贡献者的机器人。我会在等待人类维护者的过程中帮助你。

The IndexError: list index out of range occurs because the choices list is empty when the code tries to access d.choices[0].delta.content. This can happen if the API response object d does not conform to the expected structure, which should include a non-empty choices list ^[1].

The AttributeError: 'IndexError' object has no attribute 'body' is due to the code attempting to access a body attribute on an IndexError object, which does not exist. To resolve this, ensure that the exception handling code does not assume the presence of a body attribute on IndexError objects. Instead, you might want to log the exception message or handle it in a way that doesn't rely on non-existent attributes.

For debugging, you can use the logging mechanism provided by the loguru library in the codebase, which can help track such errors ^[2].
