Problem with Firebase and Listview

What is the problem with these blocks? I am getting error list index…something like that. It was working good on thunkable but having problem on makeroid. I think the error is occurring for listview component. Is there any way to solve this problem ?

Show the exact error message and not only something like error

Looks like you did something wrong in your list.
Look at the “nothing”.
It is not a component bug.
It is a logic error made by you

But Its ok with thunkable.
Why its happening with makeroid ?

I have tested with a new project but getting same problem. What is the actual problem?

I repeat, this method is working on thunkable.
