Language Server and textDocument/completion

[rajyraman]

I am unable to understand this part where it is expecting a query string called expression.

Power-Fx/src/libraries/Microsoft.PowerFx.LanguageServerProtocol/LanguageServer/LanguageServer.cs

Line 191 in 7834436

var expression = HttpUtility.ParseQueryString(uri.Query).Get("expression");

I am working on a Language Server using Omnisharp and Omnisharp does not send it to CompletionHandler, and I cannot see this in sample message as well.
