The default value was changed from None to an empty string, but the type annotation still indicates str. This could cause issues if the calling code expects None when no config value is found. Consider keeping None as the default or updating the type annotation to Optional[str].

Suggested change

	value_from_config: str = getattr(app_context.plugin_config, command_name, {}).get(self.config_option_name, "")
	value_from_config: Optional[str] = getattr(app_context.plugin_config, command_name, {}).get(self.config_option_name, None)
