Automatic count repeater item

Hello, I tried to count how many items the user input in the repeater so that at the end of the form can show how many they already listed

->schema([                       
TextInput::make("number_of_fields")
->label("Jumlah Pendaftar")
->disabled()
>placeholder(fn (Get $get) => count($get('participant'))),,
]),

->schema([                       
TextInput::make("number_of_fields")
->label("Jumlah Pendaftar")
->disabled()
>placeholder(fn (Get $get) => count($get('participant'))),,
]),

but nothing shows up with this error

TypeError
PHP 8.2.12
10.46.0
count(): Argument #1 ($value) must be of type Countable|array, null given

TypeError
