After adding the media, I can not publish the layout

Developer Experience

$layout = (new \Xibo\OAuth2\Client\Entity\XiboLayout($entityProvider))->create(‘testf’, ‘test’, ‘’, 1);

    $layoutDraft = (new \Xibo\OAuth2\Client\Entity\XiboLayout($entityProvider))->getById($layout->layoutId, 'regions,playlists,widgets');
    $layoutDraft1 = (new \Xibo\OAuth2\Client\Entity\XiboLayout($entityProvider))->checkout($layoutDraft->layoutId);
    $regions = $layoutDraft1->regions;
    $region = $regions[0];
    $region_playlistId = $region->regionPlaylist->playlistId;
    $media = [$media_id];

    $playlist = (new \Xibo\OAuth2\Client\Entity\XiboPlaylist($entityProvider))->assign($media, 10, $region_playlistId);
    $layout1 = $layoutDraft1->publish($layoutDraft1->layoutId);

This is my code to create layout, assign the media to region(from media library).
But when I check the dashboard, layout status is still draft.
Please help me how to fix this problem.
Thank you
