I think I have found the source of other problems that I reported in earlier stages (like the baseUrl not having a /). This is happening:
I add a row to a collection and prefill some data for each client. The row holds 6 images, which are empty at first and which user can set/upload. Now, when you do, in console you get this:
Wix code SDK error: The "src" property cannot be set to "". It must be a valid URL starting with "http://", "https://", or "image://".
I always ignored it, but I only now found out that after this, code in no longer executed. Can this be true? And if so, is there a way around it (except for prefilling a dummy img?).
