Language Client Not Running in Svelte Extension for VSCode

[felixhaeberle]

Describe the bug

An error was encountered in the Svelte extension for Visual Studio Code, specifically within the language client mechanism. The error occurs when attempting to send a request via the language client, with the failure message indicating that the client is not currently running.

The error suggests that the language client within the Svelte VSCode extension attempts to send a request when it is in a non-operational state (e.g., stopped, stopping, or failed to start). This situation could disrupt the functionality provided by the extension, such as IntelliSense, linting, or code formatting.

Reproduction

1. Install the Svelte extension (version 108.2.1) in Visual Studio Code on a Windows 10 system.
2. Perform actions that require communication with the language server (e.g., opening a Svelte file, editing code).
3. The error may occur under conditions where the language client has stopped or failed to initialize properly.

Expected behaviour

The language client within the Svelte extension should remain operational during active development sessions, providing continuous support for language features without interruption.

Do you have the svelte.language-server.runtime or the svelte.language-server.ls-path config?

If so, please read carefully what the description says. Most people encounter crashes because they mix up these two configs. Or set it to a non-existence path. Unless you know why you need the config, I recommend you remove them.
