[4.x]: asset.getImg() for image with only a transform url returns null

[codebarista]

What happened?

Description

I store images without URL in storage and only define a URL for the transforms. In Twig when I call the function asset.getImg('existing_transform') it returns NULL.

Steps to reproduce

1. Create filesytem "Images" w/o public URL and Base Path @storage/assets/images
2. Create filesytem "Transforms" with public URL and Base Path @webroot/assets/images
3. Create Assets Volume "Images" with Asset Filesystem "Images" and Transform Filesystem "Transforms"
4. Create Image Transforms, e.g. "large"
5. Add an image to an entry
6. Call asset.getImg('large') in a Twig template

Expected behavior

Return the image tag with image transformation.

Actual behavior

Returns null

Dirty Quick Fix

In elements/Asset.php line 1195 add the following:

if (!$volume->getFs()->hasUrls && !$transform) {
    return null;
}

Thanks for reporting that! Fixed now for the next release.

To get the fix early, change your craftcms/cms requirement in composer.json to "dev-develop as 4.1.4.1" and run composer update.

Craft 4.2.0 is out now with that fix.
