I would like to create a program that embeds the vtubestudio and voicevox api in a GUI button created with customtkinter (from now on I will abbreviate it as ctk), so that vtubestudio and voicevox will work when the button is pressed. However, when I prototype it and get it working, I get a “web socket error”. I think this probably indicates that the server side of the api is not keeping up with the processing. How can I resolve this error? Below is the program

from voicevox_adapter import VoicevoxAdapter
from play_sound import PlaySound
import pyvts
import asyncio
import customtkinter as ctk

input_str = "こんにちは"
va = VoicevoxAdapter()
ps = PlaySound("スピーカー")
data,rate = va.get_voice(input_str)
app = ctk.CTk()
app.geometry("400x240")

plugin_info = {
    "plugin_name": "trigger hotkey",
    "developer": "OverHome",
    "authentication_token_path": "./pyvts_token.txt"
}

async def voice():
    ps.play_sound(data,rate)

async def main():
    myvts = pyvts.vts(plugin_info=plugin_info)
    await myvts.connect()
    await myvts.request_authenticate_token()  # get token
    await myvts.request_authenticate()  # use token
    response_data = await myvts.request(myvts.vts_request.requestHotKeyList())
    hotkey_list = []
    for hotkey in response_data['data']['availableHotkeys']:
        hotkey_list.append(hotkey['name'])
    send_hotkey_request = myvts.vts_request.requestTriggerHotKey(hotkey_list[0])  
    return myvts,send_hotkey_request

myvts, send_hotkey_list = asyncio.run(main())

async def doing():
    await asyncio.sleep(5)
    await myvts.request(send_hotkey_list)
    await voice()

def doing_def():
    asyncio.run(doing())

button = ctk.CTkButton(app,
                       text="実行",
                       command=doing_def,
                       width=200,height=120)
button.grid(column=2,row=1)

app.mainloop()

I would like to create a program that would allow vtubestudio and voicevox to work when the button is pressed.

However, when I prototype and get it working, I get a “web socket error”. This probably indicates that the server side of the api is not keeping up with the processing.

Here is the full text of the error
