Troubleshooting Guide

When using Lovable, you may occasionally encounter technical issues. Below are common problems and recommended actions to troubleshoot and resolve them.

​

Persistent “Fix Error” Loops

Problem: Repeated failures where errors persist despite multiple attempts to fix them.

Solution:

• Approach with creativity: Adjust your input and prompts to help the AI understand the changes you’re trying to make.

• Use Chat Mode: Engage the AI in chat mode for step-by-step guidance and tailored suggestions to break the loop.

​

Setting Environment Variables

Problem: Issues may arise when configuring environment variables, particularly when working with Supabase Edge Functions and Secrets.

Solution:

• Double-check the environment variable syntax and names.

• Refer to the Supabase / Edge Functions / Secrets documentation for detailed instructions.

​

HTTP Fetch Failures

Problem: Errors during HTTP fetch requests can disrupt authentication or degrade app performance.

Solution: Copy and paste the exact error message into the chat to get context-specific advice from the AI.

​

Freezing or Loading Failures

Problem: Settings or editor pages freeze, fail to load, or do not reflect the latest updates.

Solution: Report this as a bug by creating a ticket via our feedback portal.

​

Rollback Feature Fails

Problem: Unable to revert to a previous state of the project.

Solution: Submit a bug report via our feedback portal.

​

Cloud Deployment Issues

Problem: Apps fail to redeploy or get stuck in a spinning loop during deployment.

Solution: File a bug report via our feedback portal.

​

AI-Related Errors

Problem: The AI is not resolving, hallucinating, or breaking things. Solution:

• Revert to a stable version of your application.

• For better results in future prompts:

  • Be specific and clear. Refer to our Prompting Handbook for guidance.

  • Use the select tool to precisely edit content.

  • Provide context by adding relevant documentation or a knowledge base.

​

Refactor Broke Everything in My Code

Problem: Code refactor caused major issues.

Solution:

• Revert to a stable version of your application.

• Make smaller, incremental changes and refine your prompts for clarity.

• Check your codebase history (e.g., GitHub), copy the error message, and use debugging tools like ChatGPT.

​

AI Is Not Responding

Problem: The AI is unresponsive to your changes.

Solution: Disconnect and reconnect Supabase, as this is likely related to connection issues.

​

AI Not Making Changes

Problem: The AI is not implementing expected edits.

Solution:

• If the issue persists, manually edit the code in GitHub or VSCode.

​
