Stuck on an issue?

Hi nice library, I like the Sqlite backend so much since it comes pre-installed almost everywhere. My problem is I get a database is locked error randomly.

[2019-08-22 00:08:50,358] ERROR:huey.consumer.Worker:Worker-2:Error reading from queue
Traceback (most recent call last):

sqlite3.OperationalError: database is locked

This is the code I am using.

import re

from huey import SqliteHuey
import youtube_dl

huey = SqliteHuey(filename="downloads.db")


@huey.task(retries=2, retry_delay=60)
def download(url):
    ignorable_errors = ["HTTP Error 404", "no video in this tweet"]
    status = re.match(r"https.*/status/(\d+)", url).groups(0)[0]
    ydl_opts = {"quiet": True, "outtmpl": f"{status}.%(ext)s"}
    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
        try:
            ydl.download([url])
        except Exception as e:
            error_message = str(e)
            if any(msg in error_message for msg in ignorable_errors):
                pass
            else:
                raise e
