Rahul,

Could you please try this again?

(Client-side error reporting has been changed, so the error message should actually report something now.  Also, there doesn't seem to be any attached data file.)

> Query :

> select flatten(t1.events) from `data.json` t1 inner join `data.json` t2 on t1.events[0].campaign_id = t2.events[2].campaign_id;
> +------------+

> The below 2 queries works fine 
> {code}
> 1. Without Flatten :  select * from `data.json` t1 inner join `data.json` t2 on t1.events[0].campaign_id = t2.events[2].campaign_id;
> 2. Join on simple column :  select flatten(t1.events) a from `data.json` t1 inner join `data.json` t2 on t1.uid = t2.uid;
> {code}
> There is no error in the logs. I attached the data file. Let me know if you need anything.
