Hello Community, I integrated the MMM-iCal-ToDo Module to the config.js and get the following Error. Does everyone know what to do?

Steps:

1. directory modules:
   git clone https://github.com/nixnuex/MMM-iCal-ToDo.git

2. directory modules:
   npm install

3. edit config/config.js: Just for Test (without Link to iCal)

           {
                    module: "MMM-iCal-ToDo",
                    position: "bottom_left",        // This can be any of the regions. Best results in left or right regions.
                    config: {
                            // The config property is optional.
                            // If no config is set, an example todo is shown.
                            // See 'Configuration options' for more information.
                    }
            },
   

4. Error log after npm run start:
