Steps to reproduce (using Magic Racket extension for VSCode):

• Clone the official Pollen repository
• Open pollen/render.rkt
• Try to hover over some text

Expected behavior: hovering shows a tooltip for the text (if applicable)

Actual behavior: the language server gives the following errors:

The subsequent error in documentSymbol should be fixed now. The first error that occurs in autocomplete.rkt can be fixed in the future.

The error might occurs here:
