cquery-member-hierarchy times out

[dscole]

When I run cquery-member-hierarchy on a class, emacs hangs for 10 seconds (lsp-response-timeout default value) than I get:
lsp--send-wait: Timed out while waiting for a response from the language server
I first though that maybe it's simply a hard query that requires a lot of lookup on the cquery server side, but I don't see any increased cpu usage of the cquery process.
Any ideas on how I can further debug it?
I'm suspecting that emacs-cquery might not actually be sending anything to the cquery server. How would I interact directly with the cquery server to ask it directly about member hierarchy?

Found out what is the underlying issue. It was simply removed from the cquery server:
