    change your client code to:

    const client = new Client({ authStrategy: new LocalAuth({ dataPath: "sessions", }), webVersionCache: { type: 'remote', remotePath: 'https://raw.githubusercontent.com/wppconnect-team/wa-version/main/html/2.2412.54.html', } });

    Edit LocalWebCache.js persist function adding the condition
    if(indexHtml.match(/manifest-([d.]+).json/)!=null)

    async persist(indexHtml) {
    // extract version from index (e.g. manifest-2.2206.9.json -> 2.2206.9)
    if(indexHtml.match(/manifest-([d\.]+).json/)!=null){
        const version = indexHtml.match(/manifest-([d\.]+).json/)[1];
        if(!version) return;

        const filePath = path.join(this.path, `${version}.html`);
        fs.mkdirSync(this.path, { recursive: true });
        fs.writeFileSync(filePath, indexHtml);
    }
}
