Illegal offset type error when testing file uploads with dataset.

[Ifriqiya]

I have this test:

test('that it uploads a file', function (User $user, UploadedFile $image, String $fileUploadMethod, String $fileAttribute) {
    // Arrange
    Storage::fake('public');

    // Act
    $user->$fileUploadMethod($image);

    // Assert
    expect($user->$fileAttribute)->not()->toBeEmpty();
})->with([
    'profile_photo' => fn () => [User::factory()->create(), UploadedFile::fake()->image('profile.jpg'), 
    'updateProfilePhoto', 'profile_photo_path'],
    'signature' => fn () => [User::factory()->create(), UploadedFile::fake()->image('signature.jpg'), 
    'updateSignature', 'signature_path'],
    'id' => fn () => [User::factory()->create(), UploadedFile::fake()->image('id.jpg'), 'updateId', 
    'id_path'],
    'utility_bill' => fn () => [User::factory()->create(), UploadedFile::fake()->image('bill.jpg'), 
    'updateUtilityBill', 'utility_bill_path'],
]);

it passes on the first dataset but subsequent ones fail:

What's the reason for this error and how can I resolve it.
