Discovered while attempting to use the new attributes added in #733
Essentially when the client sends a request with a progress token using named parameters and the server is using
UseSingleObjectParameterDeserialization
, vs-streamjsonrpc fails to pass along the value ofclientRequiresNamedArguments
to theJsonProgress
object.This is exactly the configuration I hit as vscode uses named parameters and we make heavy use of
UseSingleObjectParameterDeserialization
in our lsp server.The problem was that we essentially have a separate code path for handling RPC server methods that accept all args as a single argument (a special case built for LSP support), and we hadn't updated that code path to propagate the
JsonRpcMethodAttribute
in the special case.
