Form Validation Not Working Properly
Forms in your app don't validate input correctly. They might accept invalid data (empty required fields, invalid emails), show error messages that don't match the problem, or refuse to submit even with valid data.
Common Causes
- Validation only on the frontend — no server-side checks
- Validation rules don't match the actual requirements
- Error messages are generic or misleading
- Form state management is buggy — the form doesn't know which fields changed
- Submit button disabled permanently after one failed submission
How to Fix It
- Test each form field with empty, invalid, and valid data to identify which validations are broken
- Check the browser console for JavaScript errors during form submission
- Verify that the server also validates data — don't rely only on frontend validation
- Make sure the submit button re-enables after validation errors are fixed
- Check that error messages clearly indicate which field has the problem

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

The form submits but doesn't save the data. What's wrong?
The frontend form is probably submitting but the API call to save the data is failing. Check the Network tab for errors on the submit request.
I can't submit the form even with valid data. Why?
The validation logic might have a bug that always marks a field as invalid. Check the console for errors, or the submit button might be stuck in a disabled state.
