Exception thrown at hover

[mystery-e204]

An exception is thrown if a source file only contains

A%B

and the mouse hovers over B. This example might seem ridiculous (and indeed it sort of is) but in combination with pre-processor directives in more complicated source files this actually turns out to be a problem.

Here is the error I'm getting from within vsCode:

[Error - 11:22:15 AM] Request textDocument/hover failed.
