Restore the bot when the server has been restarted.

[CotulbeaCosmin]

Is there an existing issue for this?

• I have searched the existing issues.

Is this a problem caused by your code, or is it specifically because of the library?

• I have double-checked my code carefully.

Describe the bug.

Hello, I have the following issue: I activate the bot and save the session. I want to reload the bot from the session when the server is restarted, but I get this error:

Error initialize client:Failed to launch the browser process: Code: 21

stderr:

[14:14:0130/094243.901492:ERROR:chrome/browser/process_singleton_posix.cc:363] The profile appears to be in use by another Chromium process (140) on another computer (034287356bb6). Chromium has locked the profile so that it doesn't get corrupted. If you are sure no other processes are using this profile, you can unlock the profile and relaunch Chromium.

Expected Behavior

I expect to be able to reuse the same session without having to activate the bot again.

Steps to Reproduce the Bug or Issue

This is my function for restore bot after the server is started:

function restoreBots() {
const sessionsDir = path.join(__dirname, 'sessions');
if (!fs.existsSync(sessionsDir)) return;

const folders = fs.readdirSync(sessionsDir).filter(folder => folder.startsWith('session-'));
folders.forEach(folder => {
    const botId = folder.replace('session-', '');
    createBot(botId, null, null)
        .catch(err => console.error(`❌ Failed to restore bot ${botId}:`, err.message));
});

}

Im using localauth strategy, for some reason now is not creating a folder called "Sessions" and now is not creating that folder and my bot doesnt work. im not sure if this is related.

Is this the fix?
I have the same problem using LocalAuthStrategy, but I'm already using the latest version v1.34.6 which includes that PR. Specifically, this happens right after upgrading to v1.34.6.

for now set you app to use the exact specific version 1.34.4 in your package.json => "whatsapp-web.js": "1.34.4", be sure to have it exactly like this and not use the ~ or ^ as that will allow the package manager to pick the versions 1.34.6 (the one that has this issue). Then do a rm -rf node_modules inside your project and npm install that made it work for me again. (maybe you will need to delete the cache and auth folders .wwebjs_auth and .wwebjs_cache.

I was having the exact same problem this morning and after doing these steps it started working again. So it seems that something is broken in the latest version v1.34.6
