Hi @ls-infra the Promise you await on start will reject.

[ls-infra]

do you mean do a try catch for this ?

await this.wrapper.start();

[ls-infra]

btw, can we fallback to a normal text editor if WS not working >?

Yes, generally you need error handling around await.

btw, can we fallback to a normal text editor if WS not working >?

The editor and it's syntax highlighting are launched even if the language server start fails. What is currently wrong is that the wrapper doesn't flag its init is done if the language server start fails. You can work around the problem by starting them independently like done here:

Hi @ls-infra it will be released today. PR #863 is up. I want to perform some smaller corrections in the README as well.
