Troubleshooting

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

• 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.

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

• Double-check the environment variable syntax and names.

• Refer to the Supabase Docs for guidance.

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

Solution: If you’re encountering an HTTP server error when working with APIs, it typically means the server you’re trying to communicate with is not responding as expected. Here are a few steps to troubleshoot:

• Check the API Status: The issue might be on the server side. Verify if the API provider has reported downtime or maintenance.

• Review Your API Request: Ensure your request is correctly formatted, including headers, authentication tokens, and payload structure.

• Test with a Different Tool: Use tools like Postman or cURL to see if the issue persists outside of Lovable AI.

• Inspect Error Codes: HTTP errors like 500 (internal server error) indicate server-side issues, while 400 series errors often mean there’s something wrong with the request.

• Retry After Some Time: Temporary issues can be resolved by waiting and trying again later.

• Check Rate Limits: Some APIs restrict the number of requests within a time frame—exceeding limits may result in errors.

If the issue persists and is related to Lovable AI’s platform, please reach out to our support team with error details for further assistance.

Lovable AI supports Mermaid.js for creating diagrams and flowcharts directly within your AI-generated content. To use Mermaid AI with Lovable AI, follow these steps:

• Embed Mermaid syntax in your prompt or generated code blocks. Lovable AI recognizes standard Mermaid.js syntax for flowcharts, sequence diagrams, Gantt charts, and more.

• Use triple backticks (```) with “mermaid” as the language identifier to ensure proper rendering. Example: graph TD; A[Start] —> B{Decision}; B —>|Yes| C[Continue]; B —>|No| D[End];

• Verify output to ensure the diagram is correctly interpreted. If you encounter formatting issues, check for syntax errors in your Mermaid.js code.

• Optimize complexity by keeping diagrams concise, as very large or intricate diagrams may require manual adjustments.

If Mermaid AI isn’t rendering as expected within Lovable AI, feel free to reach out to our support team for assistance.

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

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

Lovable is designed to support various workflow structures, including setup wizards and assessment-style questionnaires. However, some users have encountered issues with looping errors in complex multi-step flows that generate reports at the end. If you’re experiencing this, we recommend:

1. Breaking down the flow: Ensure that each step is clearly defined and that dependencies between steps are properly structured.

2. Validating inputs at each stage: Sometimes, incorrect or unexpected inputs can cause loops—double-check validation rules.

3. Using conditional logic carefully: If your flow depends on previous responses, review the conditions to prevent unintended loops.

4. Testing with different user scenarios: Simulating various paths can help identify edge cases that may be causing issues.

5. If the problem persists, please reach out to our support team with details of your setup, and we’ll be happy to assist in troubleshooting.

• Keep prompts clear and structured.

• Use reverse meta prompting to refine results.

Problem: Remixing your project does not work.

Solution: Note that projects connected to Supabase cannot be remixed for security reasons. If this is not the case, contact support.

Problem: Large projects encounter performance issues.

Solution: We’re optimizing AI performance for large projects. Stay tuned for updates.

• Session Memory Load: Repeated edits accumulate processing history, which can slow down response time. Try refreshing your session or breaking large editing tasks into smaller segments.

• Complexity of Edits: If your document or codebase is large and complex, each subsequent edit may require more computational resources. Consider refactoring your codebase by structuring edits more efficiently.

• Browser Performance: Running Lovable AI for an extended period with intensive edits may strain browser memory. Restarting your browser or using a different one can help.

If performance degradation continues despite these optimizations, please reach out to our support team with details about your use case for further assistance.

If you encounter any other issues, reach out via our feedback portal or explore our prompting guide.

If you notice that your recent commits are missing from your Lovable project, it could be because the commits were made to a different branch on GitHub. Lovable currently only tracks commits made to the default branch (usually main or master). If you’ve been working on a new branch and haven’t merged it into the default branch, those commits won’t be picked up by Lovable.

1. Merge your changes into the default branch.

2. If you’re working on a new branch, consider switching back to the default branch for commits you want to appear in Lovable.

If you encounter difficulties connecting or authenticating with integrations, try the following:

1. Double-check API credentials for accuracy.
2. Ensure the required scopes or permissions are enabled.
3. Verify network connectivity, as firewalls or proxies may block connections.

Refer to GitHub Integration or Supabase Integration for detailed setup instructions.

Lovable enables secure storage of API keys within your project settings (accessible from the Settings sidebar). To maintain security:

• Store your keys in this designated secure location.
• Avoid sharing them with others or using them in prompts unless absolutely necessary.

This ensures your credentials are protected and reduces the risk of misuse.

If you’re not a developer, integrating APIs might feel overwhelming. Lovable simplifies this with its in-chat configuration. For unsupported APIs, join the Lovable community on Discord for help or request new integrations here.

Errors in edge functions can disrupt workflows. To resolve these issues:

1. Review edge function logs to identify and fix errors.
2. Ensure all required dependencies are installed.
3. Confirm that environment variables are correctly configured.

For more information, refer to Supabase’s edge function examples for best practices.

Managing sessions and data effectively is critical for smooth app performance. Follow these tips:

• Use Supabase’s real-time features (or similar services) for seamless data syncing.
• Ask Lovable to implement strong authentication and token refresh mechanisms for session management.
• Regularly verify that your database schema is up-to-date to prevent potential data integrity issues.

For smooth repository management and account syncing:

• Verify that GitHub repository access permissions are correctly configured.
• Use Lovable’s built-in rollback feature for undoing accidental changes, as your projects are automatically backed up.

This ensures safe and reliable version control for your projects.

• Ensure the correct headers (Access-Control-Allow-Origin).

• Check the API server for CORS policy settings.

• Use a proxy or adjust the front-end request mode.

ARIA errors usually occur when accessibility attributes are missing or incorrectly implemented. To avoid these:

• Use semantic HTML (e.g., <button> instead of <div> for clickable items).

• Follow ARIA best practices when defining elements.

• Test with accessibility tools (e.g., Chrome DevTools).

If RLS is enabled:

• Define clear policies for who can read/write data.

• Test queries using Supabase SQL editor.

• Ensure users are properly authenticated before making requests.
