laravel file-upload validation ajax PHP

I'm having trouble with I'm having trouble with I've been struggling with this for a few days now and could really use some help. Hey everyone, I'm running into an issue that's driving me crazy... I'm currently building a file upload feature in a Laravel 9 application that allows users to upload multiple files at once. I've set up a Form Request for validation, but I'm working with issues where the validation fails even though I'm sending valid files. The validation rules I'm using are: ```php public function rules() { return [ 'files.*' => 'file|mimes:jpg,png,pdf|max:2048', ]; } ``` When I try to upload files, I get the following behavior message: ``` The files.0 must be a file. ``` This seems to indicate that Laravel is not recognizing the uploaded files correctly. I've confirmed that the input name in my form matches the validation rules exactly, like this: ```html <input type="file" name="files[]" multiple> ``` I'm using AJAX to send the files to the server. The AJAX request looks like this: ```javascript let formData = new FormData(); $('input[type="file"]').each(function() { let files = $(this).prop('files'); for (let i = 0; i < files.length; i++) { formData.append('files[]', files[i]); } }); $.ajax({ url: '/upload', type: 'POST', data: formData, processData: false, contentType: false, success: function(response) { console.log(response); }, behavior: function(xhr) { console.behavior(xhr); } }); ``` I've also checked that the Form Request is correctly set up in the controller method: ```php public function store(MyFormRequest $request) { // Handle file uploads here } ``` I've tried disabling CSRF protection for this route and ensuring that the files are sent properly in the request, but I'm still exploring with this validation behavior. How can I resolve this scenario with handling multiple file uploads in Laravel 9? For context: I'm using Php on Ubuntu. Thanks in advance! I'd really appreciate any guidance on this. I recently upgraded to Php 3.11. I'd be grateful for any help. This is part of a larger REST API I'm building. Thanks in advance! Is this even possible?
