Id is already exist with another component please use another ID
Please post a proper blocks, half of your blocks are missing. By way this issue raised in if then condition your “tiny db value” is not a empty list. Call the same procedure, with same “id” cause this issue.
Look here, I think your blocks setup is wrong. Bcz you put For each no. Inside a for each item. When for each runs it triggers for each no. Every time in a loop and your number block start from 1 every time that is why this happened. Try to use both blocks separately.
