Can't input queries while debugging.

[MergeCommits]

Hello,

Whenever I begin a debugging process in the extension I get this error in the debug console:

ERROR: /.vscode/extensions/arthurwang.vsc-prolog-0.8.23/out/src/features/debugger.pl:11:
    source_sink `library(http/json)' does not exist
Warning: /.vscode/extensions/arthurwang.vsc-prolog-0.8.23/out/src/features/debugger.pl:11:

Debugging still partly works regardless of this error, as when I write:

tom(cat).

start :-
    tom(cat).

Writing start will work as intended.

However straight-up queries like tom(cat). do not work and produce the error:

tom(cat).
ERROR: Syntax error: Unbalanced operator
ERROR: call((tom(cat)
ERROR: ** here **
ERROR: .)) . 

Not really sure if these two issues are unrelated, since I'm not entirely sure if the latter is an issue with my syntax for queries. Is there something special I need to do for those?

This was done using VSC-Prolog v0.8.23 running on Code v1.30.2, OSX 10.14.2.

Thank you for your time.
