v0.50.0 throws "[TypeError] no implicit conversion of nil into String" / "[NameError] uninitialized constant"

Problem

Solargraph gem v0.49.0 seems to work fine for me. However with v0.50.0, whenever I open a .rb file in VS Code, I repeatedly get the following errors no matter where I click in the file:

[Error - 12:36:41 AM] Request textDocument/hover failed.
  Message: [TypeError] no implicit conversion of nil into String
  Code: -32603 
[Error - 12:36:41 AM] Request textDocument/documentHighlight failed.
  Message: [TypeError] no implicit conversion of nil into String
  Code: -32603

I saw the following error pop up as well at one point, but I'm not sure how to reproduce it:

[Error - 12:36:41 AM] Request textDocument/formatting failed.
  Message: [NameError] uninitialized constant Solargraph::LanguageServer::Message::TextDocument::Formatting::RuboCop

I do not get these errors when using gem v0.49.0.
