“Try to Fix” error loops

Building with Lovable makes coding faster and more intuitive—but even the best AI development tools can occasionally hit a snag. Sometimes your code won’t run as expected, or you might notice unexpected behavior where the AI interprets your intent incorrectly.

Here’s a step-by-step guide to help you navigate issues and get back on track:

1

Use the Try to Fix Button First

Click the Try to Fix button when an error shows up. Lovable will scan your logs, detect the issue, and attempt a quick fix. It’s your fastest first move. If that doesn’t work, it’s time to dig deeper.

2

Diagnose Unexpected Behavior

Your code may run without errors but not behave as intended. That’s unexpected behavior—harder to spot and harder to fix. Try this:

  • Review your original prompt to confirm your instructions.
  • Break it down: Check individual components and logic.
  • Add visuals: Use screenshots to clarify what went wrong.
3

Write More Effective Prompts

Clear, structured prompts lead to better results. Use this format:

  1. Project Overview – What are you building?
  2. Page Structure – List key pages/components.
  3. Navigation Logic – Describe user flow.
  4. Visual Aids – Upload wireframes or screenshots.
  5. Implementation Steps – Lay out the build order.

Build in Logical Order

Structure matters. Follow this recommended flow:

  1. Create layout and pages.
  2. Connect Supabase or your backend.
  3. Set up authentication and user roles.
  4. Plan and organize feature logic.
  5. Prompt Lovable to implement features.

Use Chat Mode for Clarity

When unsure, switch to Chat Mode:

  • Ask Lovable to analyze your project state.
  • Request a recap of attempted solutions.
  • Prompt for new directions to solve persistent problems.

If You're Still Stuck: Advanced Tactics

Still no luck? Try this:

  • Be exact – Describe the bug and your expectations clearly.
  • Use images – Screenshots or videos help illustrate problems.
  • Ask directly – “What else can we try?”
  • Rollback – Restore to a working version and rebuild incrementally.

Comprehensive Debugging Manual

This document or this website were written by a Lovable power user in our Discord community.

​
How to use it

  1. Download it as Comprehensive_Debugging_Manual.md.
  2. Upload it to your GitHub project.
  3. Prompt Lovable: “Read this document. Let me know if it helps. Then create a prompt I should use to troubleshoot this issue.”
  4. After Lovable responds, say: “Before you proceed, explain in detail why you think this will work. Wait for my approval.”

This ensures deeper understanding before implementing any fix.
