Django POST请求报错：无法访问未关联值的response变量

我在消息类中编写了如下代码：

response: Dict[str, Any] | None = None
try:
    response = self.client.post("url/", data=payload)

    if not response or not response.get("ok"):
        logger.warning(
            "[MessageService sync_chat] " +
            "Server responded without confirmation (ok=False) for chat '%s'",
            chat.chat_id
        )
        return {"status": SyncStatus.NOT_CONFIRMED}

    self._mark_messages_as_synced(messages)
    logger.info(
        "[MessageService sync_chat] " +
        "Synced %d messages for chat '%s'",
        len(incoming_messages), chat.chat_id
    )
    return {'response': response, 'status': SyncStatus.SUCCESS}
except Exception as e:
    logger.warning(
        "[MessageService sync_chat] " + "Skipping chat '%s' due to error: %s\nResponse: %s",
        chat.chat_id, str(e)
    )
    return {"status": SyncStatus.ERROR, "reason": str(e)}

但运行时在try-except块中出现如下报错：

WARNING [MessageService sync_chat] Skipping chat '7925606@c.us' due to error:
    cannot access local variable 'response' where it is not associated with a value

尽管已经提前初始化了response变量，Python仍提示无法访问该变量，导致无法排查请求问题。

已解决 #

经排查，问题出在client.post的内部实现中：该方法抛出异常时，内部代码调用了response.text，此时response还未被赋值，从而触发了这个错误。

给后续读者的提示 #

在警告日志中添加exc_info=True参数，可打印完整的栈追踪信息，能大幅提升问题排查效率。
