Bug Description:

When I start Theia from the sources, I see this error twice in the console:

I do not see this causing any malfunction, but it does not make the development very pleasant (#12693). When I am working on something, I have to scroll through these unrelated lines in the terminal and browser logs every time.

Steps to Reproduce:

1. Start the browser example from the sources
2. Open Theia as your workspace
3. See the errors

Additional Information

• Operating System:
• Theia Version: 451464e

@planger maybe you can speak to this?

I did not yet look into the issue, however I noticed that it only occurs when there are active VS code extensions, i.e. running Theia without download:plugins will not produce these errors.

Thanks for tracking this issue! I saw this too. I found that Colin investigated a similar issue some time ago and it seems to be related to certain services that are still active and invoke features that should served by VS Code extensions, but they can't deal with the temporary document we create, so they log the error.

It seems the only way to get rid of this logged error is to find out which enabled Monaco features are causing this and turn those off.

I briefly tried a few editor options (below) and registering an empty code action provider, but this didn't help.

lightbulb: { enabled: ShowLightbulbIconMode.Off },
quickSuggestions: false,
codeActionsOnSaveTimeout: 0,
