Resolving the “Invalid response code: null” error

Last updated on Jun 11, 2026

What happened?

Some users may have recently encountered the following error while using Lempod:

Invalid response code: null

This occurred when our app couldn’t connect to the database for a few seconds due to a temporary infrastructure issue. Instead of retrying automatically, the system failed immediately and returned this confusing error message.

✅ What we've fixed

We’ve upgraded our backend systems to automatically detect and recover from database connection issues.


Now, if there's a brief hiccup:

  • The system will reconnect automatically

  • You won’t see this error again

  • Your actions will go through normally once the connection resumes

What should I do if I see this again?

You shouldn’t — but if you do, here’s what to try:

  1. Refresh the page or try again a few seconds.

  2. If the error still shows up, please contact support and let us know what action triggered it.

Thank you

We’re always working to make Lempod faster and more reliable. Thanks for your patience while we improved this behind the scenes. 🙌
