event Transformer does not play well with config:check

[ruralguru]

Does not break functionality. when running config:check i get the following errors:

[ERROR] Your configuration file contains syntax errors :( [ERROR] Line 215 column 52: Parsing error: Unexpected token .

this corresponds to the second period before date below: e.start?.date

Two questions:

1. Is there a Fix or is this the work around being to comment out the function?
2. Can somebody direct me to some documentation that explains how the event is structured?

1. ?.(optional chaining) is introduced recently (since ES2020 / Chrome 80 / NodeJS 14.0.0). But your validator esLint, which is used by config:check, might be probably old. After esLint@7.5 the validator could parse that syntax properly. (You may need to upgrade eslint npm install --save-dev eslint@^7.5)

2. See this. https://github.com/MMRIZE/MMM-CalendarExt3#handling-events
