hopefully the error explains itself. your query didn't return any results - can you share your code?
a
@billowy-army-68599
Copy code
let routeTableResult = [];
routeTableResult.push(
            aws.ec2.getRouteTable({
              subnetId: Elements,
              vpcId: id,
            })
          );
but with this query , I have not empty result and empty ... I want to avoid empty result
And I want to save values that not are empty
r
Then you should handle the error if it’s empty
a
okay! and how can i do this?
b
i'm not quite following what you're trying to do, really sorry. Can you elaborate a bit more?
a
@billowy-army-68599 I want to get the route tables with subnet id and vpc id filters. I want to save this result in an array to later work on it. I know that the query gives empty results and non-empty results, but I only want to save the non-empty results.
r
So… this array will have 1 item or be empty?
In any case, I’m not sure you would get the result you want here. The result of 
getRouteTable
is an 
Output
, which gets resolved asynchronously… so when you try to “save it for later”, things might not execute in the order you expect.

If you share more of your code and an explanation of what you’re trying to do we might be able to help point you in the right direction.
