Resize in S3 upload action

Hopefully must last plea related to the long saga of getting to grips with Docker/ S3 uploads etc. Thanks to @George for his untiring assistance and patience and to @Emiel for yesterdays assistance which was invaluable

My last problem (i hope) is using resize image with uploaded images

Obviously a normal upload / resize action would be something like

With S3 / Put image i have tried various combinations, variations of this

But there is obviously some sort of disjoint in the paths between save (should; that even be necessary?) as the image is always saved as per the original

Probably really simple but I just cant get this working. Images upload to correct location on D.O. spaces but are not resized

Anyone point me in the right direction?
