Discussion:
The error is only in the master branch, not in the 5.x branch.

@jsbautista It looks like the line raising the TypeError was added in PR #20868, maybe you can have a look?
Pinging @dalthviz about this one too. I think the problem is that the changes done in PR #20868 assume the only collections editor usage is the one in the Variable Explorer, where you can run `value['view']` without issues.

The problem is other usages (like in @jitseniesen's example) are not working with remote data, so it's possible to do that in those cases.
I will give this a check @ccordoba12 @jitseniesen  :+1:
