Undefined array key "fields" in custom_action in 1.9.2beta bricksforge 1.0.8 Nestable form

The 1.9.2 seems broken to get fields value with bricksforge 1.0.8

function test_form($form)
    $fields = $form->get_fields();
    $formId = $fields["formId"];

    if ($formId !== "slxrsx") {

    // Correct the array index to access form fields
    $email_value = $fields["form-field-email"];
    $name_value = $fields["form-field-nom"];
    $message_value = $fields["form-field-message"];

    //$user_id = get_current_user_id();

    $pdo = new PDO(
        "mysql:host=" . DBIN_HOST . ";dbname=" . DBIN_NAME,

    $sql =
        "INSERT INTO test (email, nom, message) VALUES (:email, :nom, :message)";

    $stmt = $pdo->prepare($sql);

    // Bind parameters correctly
    $stmt->bindParam(":email", $email_value, PDO::PARAM_STR);
    $stmt->bindParam(":nom", $name_value, PDO::PARAM_STR);
    $stmt->bindParam(":message", $message_value, PDO::PARAM_STR);


    $template_id = "9c60f8d1-0bfc-bd7f-73ff-8c71da452ceb";
    $to = "xxxx";
    $subject = "Hello World";
    $message = $message_value;
    $headers = [];
    $attachments = [];


add_action("bricks/form/custom_action", "test_form", 10, 1);

They update lots of things (good things !)

By the way, We cannot register with only email (in form), but seems to be vanilla Bricks bug (w/ woocommerce) : Bug report Bricks Builder Forum
