Date encoding httpsCallable

See original GitHub issue

https.onCall triggers incorrectly encode Date objects as {}.

The docs say that anything JSON encodable should work. In standard implementations Date encodes to an ISO string e.g 2018-09-10T04:07:08.901Z. While this is a one way encoding I think it would be reasonable behaviour.

Version info

firebase-functions: master firebase-tools: N/A

firebase-admin: N/A

Test case

export const listener = functions.https.onCall(async (data, context) => {
  return { date: new Date() };
}

Steps to reproduce

Were you able to successfully deploy your functions?

Yes

Expected behavior

Date is encoded as an ISO string, timestamp or using a custom Date encoding.

Actual behavior

Date is encoded as {}

Why don’t you fix this with just if _.isDate(data) { return data.toJSON() } as proposed here https://stackoverflow.com/questions/53520674/returning-dates-server-timestamps-in-cloud-callable-functions ?
