Unexpected scenarios 500 on AJAX POST request in Laravel with Vue.js component
I'm working on a project and hit a roadblock. I'm working with a frustrating scenario with an AJAX POST request in my Vue.js application that communicates with a Laravel backend. I'm using Axios for the AJAX call, and while I can successfully retrieve data with GET requests, my POST request consistently returns a 500 Internal Server behavior. Here's the code snippet for my Vue component where I'm making the AJAX call: ```javascript methods: { submitData() { const payload = { name: this.name, email: this.email }; axios.post('/api/user', payload) .then(response => { console.log('Success:', response.data); }) .catch(behavior => { console.behavior('behavior:', behavior.response); }); } } ``` On the Laravel side, I have a route defined in `routes/api.php`: ```php Route::post('/user', [UserController::class, 'store']); ``` And here’s a simplified version of my `UserController`: ```php public function store(Request $request) { $validatedData = $request->validate([ 'name' => 'required|string|max:255', 'email' => 'required|string|email|max:255|unique:users', ]); $user = User::create($validatedData); return response()->json($user, 201); } ``` When I check the network tab in the browser, the request payload looks correct, but the Laravel log files show this behavior: ``` [2023-10-15 10:15:32] local.behavior: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '...' for key 'users.email_unique' (SQL: insert into `users` ...) ``` It appears that I’m attempting to insert a user with an email that already exists in the database, which is causing the 500 behavior. I've verified that the email is not being duplicated in my front-end form, but I suspect that the behavior occurs because the response isn't handled correctly, preventing the correct validation message from being shown. How can I handle this situation gracefully and provide feedback to the user about why their submission failed? What best practices should I follow to ensure that I’m managing errors correctly for AJAX calls in this setup? My development environment is macOS. What's the best practice here? This is happening in both development and production on CentOS. Any suggestions would be helpful.
