When I create the variable in line 34 I get this error: java.lang.IndexOutOfBoundsException: Index 0 out of bounds for length 0 << Code Omitted >>

It is trying to tell you that the returned list is empty and therefore you cannot get any element from it. First check to ensure the list is NOT empty before trying to get an element from it.

Fixed it. Thanks for the explanation.

I'm just taking the first million (based on the url of my account, there shouldn't be more than 100000 users).

Ah, but noone has a block when a scenario that uses it is first uploaded. Only when the scenario first does a "store" on a user does that user get a block; and that user must be signed in even for that to happen. So you might, over time, accumulate 100+ UserInfo blocks on a scenario.

You have written 43 and 83 Do u wanted to write 42 and 82 or u have written correct

Strange, looks now like 36 thru 51 and 76 thru 91. I think you may have edited the post. Also adding crates should probably be included within the initialize method.

Sorry for that I edited it 3 timea and posted it

You probably have two classes that unconditionally initiate one another (or multiple classes creating a loop of initiations).

I still think this is the issue.

While loop

Could you please name one thing that can go wrong with a while loop

One thing that can go wrong is that the condition to loop remains true indefinitely -- so, execution is "stuck" in the loop. It will make it seem the scenario is "frozen" as the process never completes.
