@kaiyan-sheng Did something changed recently in the package or maybe it's the recent changes in the installation @neptunian @jen-huang ?

I did also see this last week but did not get to report it yet.

@ph this has been around for a little bit. Search "flatten-able" in our Slack. @ruflin saw it last week and I encountered it while researching #66301

It noticed "collect logs from AWS metrics" was disabled in https://user-images.githubusercontent.com/14081635/81741497-e6014880-945b-11ea-93e5-5f96e988732e.png

In my experience, disabling that allowed installation and enabling triggered that error.

I am looking to fix the issue, it seems trivial to fix, it happens when we have a validation error at the input level and we do not have stream variables and aws is probably the only package with that.
