Silly me… after re-re-re-re-re-re-checking, indeed I found a server action with the load image step selected in my main layout…
I don’t even know why this server action was called here because I don’t need it here at all!
Thanks a lot @Teodor and @George, you were right since the beginning!
And thank your for your hard work and this amazing 3.2.2 release, as always!
