Steps To Reproduce

// wa_automate_api.js
// WhatsApp automation API using open-wa/wa-automate-nodejs
// Run: npx wa-automate --help for CLI usage or use as a library

const wa = require('@open-wa/wa-automate');
const express = require('express');
const multer = require('multer');
const fs = require('fs');
const path = require('path');

const app = express();
const port = 3001;
const upload = multer({ dest: 'uploads/' });
const filePath = "C:\Users\virch\CascadeProjects\invitationcard\output_invitations\test.png"
//const filePath = "C:\Viral\skc\test.pdf"
let clientInstance = null;

wa.create({
sessionId: 'INVITE',
multiDevice: true,
headless: false,
qrTimeout: 0,
authTimeout: 0,
cacheEnabled: true,
useChrome: true,
killProcessOnBrowserClose: false,
chromiumArgs: ['--no-sandbox', '--disable-setuid-sandbox'],
}).then(async client => {
clientInstance = client;
console.log('✅ open-wa client ready!');
// Send a message to a contact (replace with actual number)
const id = 'xxxxxxxxxx@c.us'; // Contact WhatsApp ID (no + or spaces)
try {
console.log('✅ xxxxxxxxxx@c.us!');
if (!require('fs').existsSync(filePath)) {
console.log('❌ File not found:', filePath);
return;
}

    const imageBase64 = fs.readFileSync(filePath, 'base64');
    await client.sendFile(id,  `data:image/png;base64,${imageBase64}`, 'image.png', 'Please see attached document.');
    console.log('✅ File sent with caption');
  } catch (e) {
    console.error('❌ Error sending file:', e);
  }

}).catch(e => {
console.error('❌ open-wa client error:', e);
});

app.post('/send', upload.single('image'), async (req, res) => {
if (!clientInstance) return res.status(503).json({ error: 'Client not ready' });
const { number, message } = req.body;
if (!number) return res.status(400).json({ error: 'Missing number' });
const chatId = number.includes('@c.us') ? number : ${number}@c.us;

try {
if (req.file) {
const filePath = path.join(__dirname, req.file.path);
const mediaData = fs.readFileSync(filePath, { encoding: 'base64' });
await clientInstance.sendImage(chatId, filePath, path.basename(filePath), message || '');
fs.unlinkSync(filePath);
} else if (message) {
await clientInstance.sendText(chatId, message);
} else {

}
res.json({ status: 'sent', to: chatId });
} catch (err) {
res.status(500).json({ error: err.message });
}
});

app.listen(port, () => {
console.log(🚀 open-wa API server running at http://localhost:${port});
});
