Call to undefined method App\Models\User::createToken()

Title: Call to undefined method App\Models\User::createToken() Body: The error "Call to undefined method App\Models\User::createToken()" typically occurs when you try to call a non-existent or unsupported method on an object of class User. In your example code, you've implemented a user registration system utilizing Laravel and PHP 7.4. However, the error can indicate that some configuration issues are present in either your controller, model, or authentication files. Let us break down each potential cause step by step to help resolve this issue. 1. Check your Controller code: Ensure your code is using the correct methods from the User model when creating new users. The line of code "User::create($dataArray);" seems to be fine as `create()` is a valid method on the User model class. However, if you're making further calls like the one causing an issue, double-check that they exist and are defined correctly. 2. Review your Model code: Ensure methods in your models follow Laravel conventions which include the "public function" declaration when defining custom methods, for instance, you have a default "create()" method already defined in Eloquent's model class. Check if you've overridden this with a custom implementation or if there are any other created functions that might be causing the issue. 3. Recheck your Authentication configuration: As an API-based system, it's likely you are using Passport (Laravel's authentication package) to handle authentication and authorization in your application. The "auth.php" file governs all these settings. To validate that the issue is not in this aspect: - Ensure the configuration is correct. For instance, your code snippet calls a method 'createToken()' which isn't explicitly defined within your User model but is already available with Passport. Your User model code should not directly create tokens as this functionality is handled by the OAuth2 authentication system provided by Laravel. - Check to make sure that your Passport setup is using the correct driver and model for both the "web" and "api" guards. Specifically, ensure that these drivers are linked to your User table or model correctly. - If you're overriding any default methods in your authentication code, make sure they correspond with the existing methods within Laravel's default configuration. 4. Ensure correct installation of Passport: As seen in the given error log, the command "php artisan passport:install --force" was executed three times suggesting either a misconfiguration or an attempt by you to reinstall your application settings. If this is indeed causing issues with authentication, ensure that this command is run once properly to properly configure Passport and avoid further complications. Ensuring the correct implementation of Laravel's standard conventions and double-checking configuration files should help resolve the issue. To avoid future errors, always check your code for duplicated or unnecessary configurations, and make sure the functionality aligns with Laravel's official documentation and best practices.
