Vite HMR is not working because a file is imported with the wrong case
Vite detects a file change but the HMR is not working.
Vite sees the changed file, but Hot Module Replacement fails because the import path casing does not exactly match the real file path.
Observed message
Vite detects a file change but the HMR is not working.
Why it happens
- A file is imported with different letter casing than the actual file on disk.
- Cross-platform filesystem differences hide a casing mismatch during development.
- Refactoring renamed a file but some imports still use stale casing.
How to fix it
- Update import paths so they exactly match the real filename casing.
- Search the codebase for inconsistent imports of the same file.
- Restart the dev server after correcting the import mismatch.
