monaco-vscode-api: Uncaught Error: Cannot have two contributions with the same id editor.contrib.referencesController

I am trying to update my monaco editor to 1.41.0, with the recommended monaco-langaugeclient 6.4.6 and monaco-vscode-api 1.81.7. I used to have some code that worked using monaco-editor 0.36 and now have to update the entire service setup.

I have followed to demo (I think), calling the initialize function like this:

    await initializeMonacoServices({
        ...getConfigurationServiceOverride(monaco.Uri.file("/tmp")),
        ...getEditorServiceOverride(openEditor),
        ...getLanguagesServiceOverride(),
        ...getModelServiceOverride(),
        ...getSnippetServiceOverride(),
        ...getStorageServiceOverride(),
    });

I think this is probably more than what I even need 😉 But whatever I do (even when calling the initialize method without any services) I do run into this error:

Uncaught Error: Cannot have two contributions with the same id editor.contrib.referencesController

I am pretty sure I am just using this wrong, but I would still appreciate any ideas on how I can debug this.
