[educgoncalves]

Pessoal,
Trecho do código dando erro no getContact ou getContactById

    const chatId = msg.from;
    const contact = await client.getContactById(chatId); //Pegando o contato
    const cliente = contact.pushname; //Pegando o nome do contato
    const telefone = contact.number;  //Pegando o telefone do contato

Solução provisória para o problema

    const chatId = msg.from;
    const authorId = msg.author || chatId; 
    const cliente =  msg._data.notifyName || 'Desconhecido';
    const telefone = authorId.split('@')[0];
