Any ideas what might be causing this failure in a test? I saw it back in March, and I think wiping lmbd_store fixed it. Doesn’t do the trick here.

Exception: Types that will be passed as Params at the root of a graph need to be registered via RootRule:
E             Any

I isolated it down to specifically in a test passing

TargetsWithOrigins([])

as a member of

Params

in

self.request_single_product

. I have no idea where to start with debugging this

this behavior is literally tested for some reason

What do you mean by “literally tested”? Also see https://pantsbuild.slack.com/archives/C0D7TNJHL/p1587504459295400 for what the issue was
