Query error: Internal error generating query plan (visual AND Plan Text)

Summary: When executing a query with a correlated subquery, I get an error.

Repro:

1. Paste the the attached query.
2. Execute. It can be on any bucket.
3. Click "Plan" or "Plan Text"

Expected:

For "Plan", a visualized query plan. For "Plan Text", the raw information of the query plan.

Actual:

For "Plan", see planErrorMessage.txt. For "Plan Text", see planTextErrorMessage.png

Notes:

The query executes without error. It's only when clicking "Plan" or "Plan Text" is there an error.

This error happens on any bucket/collection, regardless of indexing. You can sub out "AdventureWorks2016.Production.Product" in query.n1ql to `travel-sample` or whatever and still get the error.
