Failed to deserialize InitializeParams: missing field `requests`

[afonsolage]

After updating to the latested Rust Analyzer (be it 2020-11-02 or nightly) it always crash. I've already tried with latest VSIX and the stable one, no luck. It doesn't work either with Nightly rust or Stable rust, doesn't matter.

Here is the full error:

I also got the following message:

The Rust Analyzer server crashed 5 times in the last 3 minutes. The server will not be restarted.

I'm using Windows 10 with the following env:

Tested with latested nighly. Same issue.

[matklad]

Do you have rust-lang.rust extension installed by any chance?

[afonsolage]

Yes, I do. v0.7.8 from oficial extensions.

[matklad]

I think this error might originate from rust-lang.rust. In general, it is recommended to use either rust-lang.rust with RLS, or matklad.rust-analyzer with rust-analyzer.

[afonsolage]

Didn't know rust-lang.rust was optional, I always used both as required.

Indeed it don't shows any erros anymore.

Thanks!
