    await browser.close();
} catch (err) {
    console.error(`${err}. Icon command.`);
    lastMsg.then(msg => msg.delete());
    return msg.channel.send(msgEmbed.setTitle('An error has occurred, retry the command. If the error keeps happening contact @Staff'));
         }
};

The error that is being logged: Error: Protocol error (Target.setAutoAttach): Target closed..

This is for a custom command on a Discord bot, when I was testing locally this worked perfectly fine. Almost never got any errors.

The moment I deployed my code to Heroku so it can be online all the time it gave me an instant error like this, and the error message happens almost instantly after the command was typed in so it must be happening very early in the process. Not sure if this is a Playwright error or something to do with Heroku but any help here would be very appreciated.
