Magento 2 Admin Form: form_id and title Fields Not Populating Correctly

I’m trying to create a simple Magento 2 admin form with the following requirements, but I’m running into issues. Here’s what I want:

Form Fields:

• A hidden form_id field with a value of 1.
• A visible title field with an initial value of “Default Value”. This should be retrieved from the data provider
• Data Provider
• UI Component XML
• The form_id field should be invisible, and the title field should be visible.
• The form is standalone and does not rely on a grid or collection.

FormDataProvider Class:

<?php
declare(strict_types=1);

namespace SwiftsolutionsMobileAdminPanelModel;

use MagentoUiDataProviderAbstractDataProvider;
use MagentoFrameworkAppRequestInterface;

/**
 * DataProvider component.
 */
class FormDataProvider extends AbstractDataProvider
{
    /**
     * @var array
     */
    private $loadedData;

    /**
     * @var RequestInterface
     */
    protected $request;

    /**
     * @param string $name
     * @param string $primaryFieldName
     * @param string $requestFieldName
     * @param RequestInterface $request
     * @param array $meta
     * @param array $data
     */
    public function __construct(
        $name,
        $primaryFieldName,
        $requestFieldName,
        RequestInterface $request,
        array $meta = [],
        array $data = []
    ) {
        parent::__construct($name, $primaryFieldName, $requestFieldName, $meta, $data);
        $this->request = $request;
    }

    /**
     * @return array
     */
    public function getData(): array
    {
        if (isset($this->loadedData)) {
            return $this->loadedData;
        }

        // Set a default form_id (e.g., 1)
        $formId = 1;

        // Load your data here. For example:
        $this->loadedData = [
            $formId => [
                'form_id' => $formId, // Populate the invisible form_id field
                'title' => 'Default Value' // Populate the visible title field
            ]
        ];

        return $this->loadedData;
    }

    /**
     * Override addFilter to avoid collection usage.
     *
     * @param MagentoFrameworkApiFilter $filter
     * @return void
     */
    public function addFilter(MagentoFrameworkApiFilter $filter)
    {
        // Do nothing, as we don't need filtering for this data provider
    }

    /**
     * Override getSearchResult to avoid collection usage.
     *
     * @return MagentoFrameworkApiSearchSearchResultInterface
     */
    public function getSearchResult()
    {
        // Return an empty search result
        return new MagentoFrameworkApiSearchSearchResult();
    }
}

The Problem:
Despite the above implementation, the title field is not being populated with the Default Value. The form_id field is also not being set correctly. When I debug the request, I see that form_id is NULL.

Why the current implementation isn’t working.
