Can not get third party extension setting options by PreferenceService

[wss29]

Hi,
I install llvm-vs-code-extensions.vscode-clangd-0.1.29 in theia plugins, I want to get 'clangd.path' of its setting, I use follow code

     await this.preferenceService.ready;
    const exist = this.preferenceService.get('clangd.path');

const exist = this.preferenceService.get('clangd.path'); always return undefine, even I have set value for 'clangd.path' from the UI setting. It is strange, Does I use correct method to get?

Hey @wss29,

I'm not sure waiting until the preference service is ready is enough - the backend registers the extension preferences with a bit of delay in the frontend. You probably need to wait until the HostedPluginSupport#didStart promise is ready:

@inject(HostedPluginSupport)
private readonly hostedPluginSupport: HostedPluginSupport;
...
await this.preferenceService.ready;
await this.hostedPluginSupport.didStart;
const exist = this.preferenceService.get('clangd.path');
