Fetching via Admin API?

OK, here's some additional data.

As mentioned, every image URL is coming out using the "res" sub-domain instead of "api-eu".

File URI: cloudinary://images/2023-03/background.png

becomes

Image URI: https://res.cloudinary.com/xxx/image/upload/s--krZz8bFO--/c_fill%2Ch_243%2Cw_360/v1/images/2023-03/background.png?itok=IOSup1_k

But the Cloudinary config looks like this:

Cloudinary\Configuration\Configuration Object
(
    [sections:protected] => Array
        (
            [0] => cloud
            [1] => api
            [2] => url
            [3] => tag
            [4] => responsive_breakpoints
            [5] => auth_token
            [6] => logging
        )

    [includeSensitive:protected] => 1
    [cloud] => Cloudinary\Configuration\CloudConfig Object
        (
            [cloudName] => xxx
            [apiKey] => 999999999999999
            [apiSecret] => pppppppppppppppppppp
            [oauthToken] => 
            [signatureAlgorithm:protected] => 
            [explicitlySetKeys:protected] => Array
                (
                    [cloudName] => 1
                    [apiKey] => 1
                    [apiSecret] => 1
                )

        )

    [api] => Cloudinary\Configuration\ApiConfig Object
        (
            [uploadPrefix:protected] => https://api-eu.cloudinary.com
            [apiProxy] => 
            [connectionTimeout] => 
            [timeout:protected] => 
            [uploadTimeout:protected] => 
            [chunkSize:protected] => 
            [callbackUrl] => 
            [explicitlySetKeys:protected] => Array
                (
                    [uploadPrefix] => 1
                )

        )
...the rest is empty.

Nothing I do forces it to use "api-eu" instead of "res" - I have changed everything I can find.

Hi,

There are plenty of fixes in ✨ Create a Cloudinary media source instead of a separate media type Fixed
It will be a new major version and there is upgrade path from 2.x

You could try to switch to that fork and recheck or wait for new release

Admin API is used for many features in the current implementation, I will check if it makes sense, if it's mandotary and will be back to you later with more information
