Erro on Firefox/Chrome console when close/save settings

[SinisterRj]

Description

I get this error everytime that I need to close or save the octoprint's settings when UI Customizer is active:

Error calling onSettingsHidden on view model UICustomizerViewModel : Empty streamUrl. Cannot determine stream type.

Can you recreate it? Yes

Did you try disabling plugins? Yes. The problem only happen with UI Costomizer.
