'one_time_key_counts' is a required property

[nexy7574]

I have been encountering this so much while trying to start a client with matrix-nio. This error is logged and appears to actually be a fatal error, as the client is entirely unresponsive - it cannot accept invites, thus cannot join a room, or... do anything.

I have posted a gist here: https://gist.github.com/nexy7574/a38096cccda0aeb585ff5de8e7116cbd

Repro code (stripped down, using nio-bot v1.1.1, which uses matrix-nio 0.24.0):

import json
import logging
from pathlib import Path
from contextlib import asynccontextmanager

import httpx
from ollama import AsyncClient

import niobot
import tomllib

if not Path("./config.toml").exists():
    raise FileNotFoundError("config.toml not found in %s." % Path.cwd())
with open("./config.toml", "rb") as fd:
    config = tomllib.load(fd)

logging.basicConfig(level=config.get("log_level", "INFO"))


bot = niobot.NioBot(
    config["homeserver"],
    config["user_id"],
    config.get("device_id", "device"),
    store_path=config.get("store_path", "./data"),
    command_prefix=config.get("command_prefix", "e!"),
    owner_id=config.get("owner_id", None)
)

@bot.command("ping")
async def ping_command(ctx: niobot.Context):
    """Checks the bot is running."""
    await ctx.respond("Pong!")


bot.run(access_token=config["access_token"])

My homeserver is running dendrite, however I've had reports of this same issue on Synapse (matrix.org).
