Trying to access array offset on value of type null

Hello, I have a photo upload, but for certain photos my import crashes and I get the following message, I don’t know why, even if I suspect that it comes from the photo.

Do you have an idea?

Im just take a stab in the dark here… are you using the NEW app connect 2.
Make sure you are not using App Connect 2. Im sure i read somewhere that Drop Zone is not compatible yet… mmmm…

Maybe post to complete error…
