Calendar Event

I added events in Calendar component from 3rd party API.
the api response structure is as following:
{
“requestStatus”: {
“success”: true,
“version”: “v1”
},
“sessions”: [
{
“id”: 146879752,
“productCode”: “P0PKBN”,
“startTime”: “2020-09-24T07:00:00Z”,
“endTime”: “2020-09-24T12:00:00Z”,
“startTimeLocal”: “2020-09-24 09:00:00”,
“endTimeLocal”: “2020-09-24 14:00:00”,
“allDay”: false,
“seats”: 0,
“seatsAvailable”: 0,

So I set “api.data.sessions” to Dynamic Evens Source of the Calendar source.
and it’s “Start” attribute is “StartTimeLocal”.

But cannot see the events in the calendar.
What’s the reason?
Because “Start” attribute is the string format (“2020-09-24 09:00:00”) ?

I can see merely the wrong events in editor.
