Error: need more than 0 values to unpack

[RasecMP]

I get the error mentioned in the title after a while running main.py with the following code:

import machine
import time
from phew import server, connect_to_wifi
from phew.template import render_template

machine.Pin(13, machine.Pin.IN)
machine.Pin(18, machine.Pin.IN)

connect_to_wifi("SSID", "PASSWORD")

@server.route("/passagem", methods=["GET", "POST"])
def passagem(request):

post = request.data.get("value", None)
password = request.form.get("password", None)

if(post=="door1"):
machine.Pin(18, machine.Pin.OUT)
time.sleep(1)
machine.Pin(18, machine.Pin.IN)

elif(post=="door2"):
machine.Pin(13, machine.Pin.OUT)
time.sleep(1)
machine.Pin(13, machine.Pin.IN)

if(password == "password"):
return render_template("index.html"), 200

else:
return render_template("login.html"), 200

@server.route("/favicon.png", methods=["GET"])
def favicon(request):
return render_template("favicon.png"), 200

@server.catchall()
def catchall(request):
return "Not found", 404

server.run()

Refactoring _async def parse_headers in server.py worked for my project:

async def _parse_headers(reader):
    headers = {}
    while True:
        header_line = await reader.readline()
        if header_line == b"\r\n":
            break
        try:
            name, value = header_line.decode().strip().split(": ", 1)
        except ValueError as ex :
            return headers
        headers[name.lower()] = value
    return headers

Do not forget to adjust intent because it is 2 whitespaces in server.py.
