$collection_id = (int) elgg_extract('collection_id', $vars);

elgg_set_page_owner_guid($user->guid);

elgg_push_breadcrumb(elgg_echo('friends:collections'), elgg_generate_url('collection:access_collection:friends:owner', ['username' => $user->username]));

It seems like elgg_generate_url('collection:access_collection:friends:owner', array('username' => $user->username)) can also be of type null; however, parameter $href of elgg_push_breadcrumb() does only seem to accept false|string, maybe add an additional type check?

elgg_push_breadcrumb($collection->getDisplayName(), $collection->getURL());

echo elgg_view_page(elgg_echo('friends:collections:edit'), [
	'content' => elgg_view_form('friends/collections/edit', ['sticky_enabled' => true], [
		'collection_id' => $collection->id,
		'collection_name' => $collection->name,
	]),
	'filter_id' => 'friends_collections/edit',
]);
