JSONDecodeError in handle_rate_limit when retrying

[jayqi]

I'm running into a JSONDecodeError inside handle_rate_limit. I'm presuming this is happening when I'm hitting my webhook's rate limit and the retry code is kicking in.

Version: 1.4.1

Traceback (most recent call last):

Here's my code for invoking the webhook:

def _post_message_worker(message: str):
    try:
        webhook = DiscordWebhook(
            url=settings.ORGANIZERS_DISCORD_WEBHOOK_URL,
            content=message,
            rate_limit_retry=True,
            timeout=5,
        )
        return webhook.execute()
    except Exception as e:
        logger.exception(
            f"Failed to post message to Discord webhook: {e}", event="discord_webhook_error"
        )
