Why this happens

Lovable generates code that works functionally but may have type mismatches, missing type annotations, or implicit 'any' types that strict TypeScript catches.

Fix

Ask Lovable to fix all types

One prompt to fix everything:

Copy this prompt

Fix all TypeScript errors in this project.
Run through every file and:
1. Add proper type annotations
2. Fix any 'any' types where possible
3. Fix all red underlines in the editor
Make the project compile without errors.

Prevent this next time

Add 'use TypeScript strict mode' to your founding prompt. This catches type issues during generation rather than at deploy time.
