TypeError: listEventsCalendar.map is not a function

[sachowdhary786]

When attempting to run the project, I come across an issue where it states that listEventsCalendar.map is not a function in the EventCalendar.ts file

Obviously, the problem is that you haven't deployed the backend. Go to src/pages/index.tsx file and in line 36 replace
const listAllEventsCalendar = mapArrayEventCalendar(eventsCalendar); to const listAllEventsCalendar = (typeof eventsCalendar === 'function') ? mapArrayEventCalendar(eventsCalendar) : null;
