Bug Summary:

When typing

with Ada.

in an empty ADV file, I am not given a choice of packages but the error pops up:

Then there is a button Go to output and pressing it unveils:

[Error - 5:08:36 PM] Request textDocument/completion failed.
  Message: Exception: LANGKIT_SUPPORT.ERRORS.PRECONDITION_FAILURE (null node argument)
  Code: -32603
