I think the problem with relying on index keys is that you have to know the specific index key to work with your array. It’s easy when you know there’s only 1 data set being returned, but what if there are multiple data sets being returned? Then the index of 0 will only show 1 data set from your results rather than say 5 data sets.
I think for this it might be overkill, but I’d use a foreach loop and then check against blade_server_id.
