Actual (Problematic) Behavior

The syntax highlighting for my language wasn't working, so I tried to open the tokenization inspector, which resulted in this alert:

Expected Behavior

Expected the Token inspector to open up

Additional Context

I am using the monaco-editor-wrapper, but I don't think it causes the issue. I also can't reproduce this issue anywhere else. This is the minimal reproducible example I could get.

  const wrapper = new MonacoEditorLanguageClientWrapper();
  const userConfig: UserConfig = {
    wrapperConfig: {
      editorAppConfig: {
        $type: "classic",
        useDiffEditor: false,
        languageId: "json"
      },
    },
  };
  const htmlElement = document.getElementById("monaco-editor-root")!;
  await wrapper.initAndStart(userConfig, htmlElement);

You should open the issue on that repo, because that error doesn't come from monaco-editor itself
