Just to add to my comment above. I added a few people without pictures to complete my family tree. This is when the Java errors started to occur. I saw one of the youtube videos mentioning that one can complete a family tree without having the pictures, as a place holder with other information present. Reading the error above the first thing that comes to my mind after “null” reading ID, is precisely that. It tires to read something that does not exist.
