5.x: AssetCompressHelper script() function's return type is not compatible to HTML-Helper of cake 5.x

[cewi]

tried to update a cake 4 app to upcoming cake 5 (5.x-dev). Updated AssetCompress plugin to 5.x-dev, too (de214d1).
In my app I include a js-file like so: echo $this->AssetCompress->script('map', ['block' => 'pageScript']);
This throws AssetCompress\View\Helper\AssetCompressHelper::script(): Return value must be of type string, null returned
The js itself gets correctly built and forwarded to the HTML-Helper which returns null because the output is added to the block.
HTML-Helper's script function's public function script(array|string $url, array $options = []): ?string return type reflects this while AssetCompessHelper's script function public function script(string $file, array $options = []): string expects always a string.
Changing the return type of AssetCompessHelper's script function to ?string worked for me.
