`undefined is not iterable...` on text hover

Thanks for this great extension!

I don't know if this happens to anybody more but I have the IDE's log console plenty of the stacktrace seen below.

Extension is capable of fetch my gitsts and edit it.

To Reproduce Steps to reproduce the behavior:

Open any text file. I'd checked it with a .md (markdown)
Wait for the Intellisense suggestions
Check errors on Output panel > Log (Window) / Log (Extension Hosts)

Expected behavior No console errors or more context about it to know about solve it
