Beginner form question - Field value is 'null'

Here is my form code:

   public function form(Form $form): Form
    {
        return $form
            ->schema([
                TextInput::make('subject')->maxLength(255)->required(),
                Textarea::make('message')->minLength(10)->maxLength(50000),
            ])
            ->statePath('data');
    }

    public function create(): void
    {
        dd($this->form->getState());
    }

   public function form(Form $form): Form
    {
        return $form
            ->schema([
                TextInput::make('subject')->maxLength(255)->required(),
                Textarea::make('message')->minLength(10)->maxLength(50000),
            ])
            ->statePath('data');
    }

    public function create(): void
    {
        dd($this->form->getState());
    }

When I input values in both fields and hit Submit, the dd() output is correct for 'subject' but shows 'null' for the 'message' field. Any ideas on why this is happening?

did you add $this->form->fill() in the mount method? Could you share the whole code?

console errors?

heat23.•4w ago

@Leandro Ferreira I have "Detected multiple instances of apline running" and 500 Internal server error to /livewire/update

LeandroFerreira•4w ago

check the log

Weird that the "message" field (textarea) does not appear in the payload:

I am tailing the laravel.log, but nothing comes up

LeandroFerreira•4w ago

weird.. you should review this setup and check your livewire config https://filamentphp.com/docs/3.x/forms/installation#existing-laravel-projects

I commented out {{-- @vite('resources/js/app.js') --}} and I am getting a non-null value in the Textarea field, but still getting the 500 error in console My vite.config.js looks like this:

import { defineConfig } from 'vite';
import laravel from 'laravel-vite-plugin';

export default defineConfig({
    plugins: [
        laravel({
            input: [
                'resources/css/app.css',
                'resources/js/app.js',
            ],
            refresh: [
                'app/Livewire/**',
            ],
        }),
    ],
});

import { defineConfig } from 'vite';
import laravel from 'laravel-vite-plugin';

export default defineConfig({
    plugins: [
        laravel({
            input: [
                'resources/css/app.css',
                'resources/js/app.js',
            ],
            refresh: [
                'app/Livewire/**',
            ],
        }),
    ],
});
