Remote Session is not getting Saved

[MalikHamzaSaleemi]

Issue Description

I am using whatsapp-web.js with RemoteAuth and wwebjs-mongo to store WhatsApp sessions in MongoDB. The client connects successfully and WhatsApp becomes ready, but the remote session is not being saved properly in MongoDB.

I added a debug wrapper around store.save() to confirm whether the session upload starts or completes. The upload process starts, but no session files/data are stored in MongoDB, and the remote_session_saved event is never triggered Also when i see Mongo Db there 2 documents got created but noting insde .

Because of this, whenever I restart my server/container, WhatsApp asks me to scan the QR code again instead of restoring the previous session.

Reproduction Steps

Genertae QR code
Scan QR code
Should connect whats aap and save remote session.
Tested on Both Whats aap Business & Standard.

Code Sample

let store;
function getStore() {
  if (!store) {
    if (mongoose.connection.readyState === 1) {
      try {
        const dbName = mongoose.connection.name;
        // wwebjs-mongo 1.1.0+ prefers the mongoose instance
        store = new MongoStore({ mongoose: mongoose });
        console.log(`📦 [RemoteAuth] MongoStore connected to DB: "${dbName}"`);
        
        // 🛠️ Debug Wrapper: Catch silent upload failures with a timeout
        const originalSave = store.save.bind(store);
        store.save = async (options) => {
          const sessionName = options.session;
          console.log(`📡 [RemoteAuth] STARTING UPLOAD for ${sessionName}...`);
          console.log(`⏳ Please wait, this can take 2-3 minutes for Atlas...`);
          
          let heartbeat = setInterval(() => {
            console.log(`⏳ [RemoteAuth] Still uploading ${sessionName}... do NOT close the app.`);
          }, 20000);

const uploadPromise = originalSave(options);
          const timeoutPromise = new Promise((_, reject) => 
            setTimeout(() => reject(new Error('Upload timed out after 300s')), 300000)
          );

try {
            await Promise.race([uploadPromise, timeoutPromise]);
            clearInterval(heartbeat);
            console.log(`✅ [RemoteAuth] UPLOAD SUCCESSFUL for ${sessionName}`);
          } catch (err) {
            clearInterval(heartbeat);
            console.error(`❌ [RemoteAuth] UPLOAD FAILED for ${sessionName}:`, err.message);
          }
        };
      } catch (err) {
        console.error("❌ [RemoteAuth] Failed to create MongoStore:", err.message);
      }
    } else {
      console.error("❌ [RemoteAuth] MongoStore FAILED: Mongoose state is " + mongoose.connection.readyState);
    }
  }
  return store;
}
