Undefined method URI::siteUrl() after upgrading to 4.4.x

Does this help:

Thanks for the reply. Sadly doesn't help. I'm aware of the change, the issue is that the code in question is from CI4 itself, I can't modify it to use on prod. For some reason the site_url CI helper still uses URI, which doesn't have the ->siteUrl function, instead of SiteURI.
