TypeError while using socket.bind()

[ziGuy]

Hello,
I've cerate an issue as well. I'm not sure which is more relevant - please feel free to remove one.

I'm trying to code a webserver using usocket lib but got the following issue.
Can you please guide me to fix this issue? is it a bug?

My environment:

micropython -v
MicroPython v1.19.1-859-g41ed01f13 on 2023-02-13; linux [GCC 6.3.0] version

This happens as well on my esp32 device, which i believe running micropython 1.20

My code:

import usocket as socket

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('0.0.0.0', 80))

Traceback:

Traceback (most recent call last):
  File "boot.py", line 4, in <module>
TypeError: object with buffer protocol required

Edit:

• I've tried with latest micropython and issue still occurs:
  MicroPython v1.20.0-544-g977dc9a36 on 2023-10-02; linux [GCC 6.3.0] version
• Replacing bind function with the following didn't help:
  s.bind((b'0.0.0.0', 80))

Please try:

>>> import socket
>>> addr = socket.getaddrinfo('0.0.0.0', 80)[0][-1]
>>> s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> s.bind(addr)

Now bind gives:
OSError: [Errno 13] EACCES

When i add:
print(f"addr: {addr}")
print(f"type of addr: {type(addr)}")

I get:
addr: bytearray(b'\x02\x00\x00P\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00')
type of addr: <class 'bytearray'>

On Linux, ports below 1000 are reserved for the system and can only be accessed by root. Please try port 8080.

This worked.
This is a bit weird for me as a web server should not run as root and it should run in port 80.

Looks like there is something is wrong with my infrastructure as now i got the following, when trying to use micropyserver:
...micropyserver/micropyserver.py", line 91, in send
AttributeError: 'socket' object has no attribute 'sendall'

But this is off-topic so I'll close this thread and try to figure out what's going on.
Thank you very much for your help.
