Issues with current Obsidian

I am getting this traceback when I activate the view:

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'getRoot')
    at t.revealLeaf (app.js:1:2273618)
    at _t.activateView (plugin:contextual-sidecar:2:1428)
    at Object.callback (plugin:contextual-sidecar:2:1048)

    at e.handleKey (app.js:1:754609)
    at e.onKeyEvent (app.js:1:755865)

This is the content of that function:

  async activateView() {
    if (
      this.app.workspace.getLeavesOfType(VIEW_TYPE_CONTEXTUAL_SIDECAR).length >
      0
    ) {
      await this.app.workspace.getRightLeaf(false).setViewState({
        type: VIEW_TYPE_CONTEXTUAL_SIDECAR,
        active: true,
      });
    }

    this.app.workspace.revealLeaf(
      this.app.workspace.getLeavesOfType(VIEW_TYPE_CONTEXTUAL_SIDECAR)[0]
    );
  }

My guess is that I am using an outdated idiom, and this needs to be fixed. I'll get on it ASAP.
