List view in firebase

Hello, good morning everyone,
Before they say if I’ve done my homework ?! Yes! I already did it. I’ve searched the internet, other sources, here in the community, some gave me some suggestions has put into practice, but without result.

I have this screen, a viewer lists you, where pulls from the firebase database, some data from the database tag list.
But it turns out that when I pull in the list viewer a tag specifies where some data was not placed in that tag, it gives me this error.

Can you help me, how to do this in blocks? I already tried several blocks but without success!

Are you sure “value” is a list? Looks like it’s not.
Check that.

Yes it is a list.
Because when I click on a tag in my list viewer, where there aren’t some values ​​in the list, it works. It pulls the requested information.

Well, the error message is saying that it’s not a list. May be you need to convert it to a Kodular list? Did it work before?

Hello, @parmarparth996
The first option is not. As for the second option, it is not to give error, because I am looking for other items in the same list and gives no error.

Now i am not with my computer, i will check it tomorrow and reply you

No not that I am asking what do you want

Bcz just imagine the value of tag A is list which contains 1,2,3 so what you are doing is you are first get the length of list and on that number you are selecting a item so basically all time item will be last which is not list
