Azure Blob触发函数启动即陷入超时循环问题求助

大家好，我最近碰到个Azure Functions的麻烦事，想请各位大佬帮忙分析下：

公司里有个Azure Function突然不能正常工作了，我接手排查后发现，它刚启动就直接陷入了超时循环。因为我本身Azure Functions的经验不算丰富，想着先写个最基础的测试函数来验证环境，结果没想到这个极简版本也遇到了一模一样的问题。

我的环境信息 #

• 存储模拟工具：Azurite
• Python版本：3.11.5
• Azure.functions包版本：1.17.0

测试用的代码文件 #

function_app.py

import logging
import os
import azure.functions as func

# Create a custom logger
logger = logging.getLogger(__name__)

# Create handlers
f_handler = logging.FileHandler('file.log')
f_handler.setLevel(logging.DEBUG)

# Create formatters and add it to handlers
f_format = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
f_handler.setFormatter(f_format)

# Add handlers to the logger
logger.addHandler(f_handler)

logger.warning('This is a warning')
logger.error('This is an error')

def main(myblob: func.InputStream):
    filename = os.path.basename(myblob.name)
    content = myblob.read()
    # Your code to process the blob content goes here
    # For example, you can print the blob's filename and length
    print(f"Blob name: {filename}")
    print(f"Blob length: {len(content)} bytes")

调试遇到的困境 #

我尝试过用调试工具排查，但断点完全停不下来，只能手动暂停程序，这时候发现它已经卡在common.py的超时循环里了。

有没有朋友遇到过类似的问题？或者能给我一些排查方向的建议？
