Common Backend Issues and Solutions

Route Registration Issues

Problem: Wayfinder action file not generated, import fails Cause: Route not registered in routes/web.php Solution:

1. Check routes/web.php for the route registration
2. Verify the controller class name matches
3. Run php artisan wayfinder:generate --no-interaction
4. Verify the file exists in resources/js/actions/

See the routing-and-controllers skill for detailed workflow.

Type Generation Failures

Problem: TypeScript types not updating after PHP changes Cause: php artisan typescript:transform not run Solution:

php artisan typescript:transform

Then regenerate Wayfinder:

php artisan wayfinder:generate --no-interaction

Artisan Command Failures

Problem: Artisan commands fail or hang Cause: Configuration cache or stale files Solution:

php artisan config:clear
php artisan cache:clear
php artisan view:clear

Then retry the command.

Database Errors

Problem: Database connection fails or queries error Cause: Environment variables, migrations not run, or schema issues Solution:

1. Check .env file for correct database credentials
2. Run php artisan migrate if migrations pending
3. Check database schema with php artisan tinker and query directly

PHP Type Errors

Problem: Static analysis or runtime type errors Cause: Missing type hints or incorrect types Solution:

1. Run composer fix to check Larastan analysis
2. Add proper type hints to methods and properties
3. Check the error message for the exact location and fix

Diagnostic Commands

# Check configuration
php artisan config:show

# Run static analysis
vendor/bin/phpstan analyse

# Check routes
php artisan route:list

# Test database connection
php artisan tinker
