Decorator metadata reflection error
Unable to resolve signature of.*decorator when called as an expression
Fixes
- 1.Enable "emitDecoratorMetadata": true and "experimentalDecorators": true in tsconfig.json
- 2.Ensure reflect-metadata is imported at the application entry point
- 3.Check that the decorator factory returns the correct signature (ClassDecorator, PropertyDecorator, etc.)
