premise I'm new and I still have a lot to learn. I downloaded from git fullcalendar (https://github.com/fullcalendar/fullcalendar-angular), after opening the project, after doing npm install and ng serve I get this error message:
TypeError: Cannot read property 'start' of undefined
at Object.addParseSpanInfo

at AstTranslator.translate
at Object.astToTypescript
at TcbEventHandlerTranslator.TcbExpressionTranslator.translate
at tcbEventHandlerExpression
at tcbCreateEventHandler
at TcbUnclaimedOutputsOp.execute
at Scope.executeOp
do you have any suggestions on how to solve the problem? thanks a lot to everyone
