Issue with a couple of effects in single image style

Edit: I have misunderstood named transformations vs chained transformations so I am not sure my comments are valid anymore.

It might be unrelated, but having applied this patch I'm noticing I'm getting incorrect transformation URLs when multiple named Cloudinary transformations are being used together:

With patch:

https://res.cloudinary.com/…/image/upload/s--54KiOQT_--/t_q_auto/t_f_auto/t_w_auto/t_c_limit/v1/2020-02/gilly-uItNiF1vv4E-unsplash.jpg?itok=C-a6Cfyy

The above returns a 400 error.

I think the URL format should be:

https://res.cloudinary.com/…/image/upload/s--54KiOQT_--/q_auto,f_auto,w_auto,c_limit/v1/2020-02/gilly-uItNiF1vv4E-unsplash.jpg?itok=C-a6Cfyy

I've done some XDebugging:

With this patch, a call to Cloudinary::cloudinary_url($source, $options); is returning the incorrect URL ‌https://res.cloudinary.com/dywlbz3eg/image/upload/s--54KiOQT_--/t_q_auto... – I suspect we are passing data to the Cloudinary SDK that it does not expect.

I think this data structure might not be what the Cloudinary SDK expects?

Changing status back to needs review.
