Luxon is failing to parse this date format

I’m trying to figure out why luxon is failing to parse this date format.

This is the original value I have: 2019-04-23T23:15:07.910Z.

What format is this (it looks like an iso format).

Code snippet:

console.log('document.lastUpdatedAt = ', document.lastUpdatedAt)

const fromISO = DateTime.fromISO(document.lastUpdatedAt)
console.log('fromISO = ', fromISO)

const fromSQL = DateTime.fromSQL(document.lastUpdatedAt)
console.log('fromSQL = ', fromSQL)

const fromHTTP = DateTime.fromHTTP(document.lastUpdatedAt)
console.log('fromHTTP = ', fromHTTP)

Output from snippet above:

document.lastUpdatedAt =  2019-04-23T23:15:07.910Z
test =  test
fromISO =  DateTime {
  ts: 1556062543882,

     explanation:
      'the input "Tue Apr 23 2019 16:15:07 GMT-0700 (Pacific Daylight Time)" can't be parsed as ISO 8601' },
  weekData: null,
  c: null,
  o: null,
  isLuxonDateTime: true }

Ahh just figured it out. Turns out 2019-04-23T23:15:07.910Z is actually a javascript date object.

This means I needed to do const fromJSDate = DateTime.fromJSDate(document.lastUpdatedAt)
