This looks similar to what was solved in #7205, except with maps instead of sets.

I'd like to figure out what changes between rc1 and rc2 to trigger it though

[hngkr]

At this point of the evening, I'm certainly not clever enough to look thru' what #7205 does, but I just tried with master - and it's complaining about the same thing as above.

[jbardin]

This regression is a side effect of #7082.

[glasser]

Running into this one too.

Was this auto-closed on accident?

[jbardin]

Hi @colemickens,

Nope, but the links between the issues are confusing, both because I mentioned the this issue in the code, and didn't change the PR message to include the "fixes" notation. Sorry about that.

This was closed by #7249

[hngkr]

I'll just add that I just tried to rerun the script from the reported issue above. I used Terraform from the master branch, and I'm no longer getting the error message. Everything works beautifully. Thanks a lot!
