vs-code error after successful installation on 1.19.0-nightly

[hackeryarn]

Every time I try to launch vs-code with RLS running I get the below error, and the status or RLS remains as crashed.

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: ErrorImpl { code: Message("missing field `experimental`"), line: 0, column: 0 }', src\libcore\result.rs:859
note: Run with `RUST_BACKTRACE=1` for a backtrace.
[Error - 5:19:45 PM] Connection to server got closed. Server will not be restarted.

Same here, using https://github.com/editor-rs/vscode-rust on rustc 1.19.0-nightly (826d8f385 2017-05-13).

backtrase:
