Firebase-admin-node: Firestore "timestampsInSnapshots setting now defaults to true" error in Cloud Functions

[mikemclin]

[REQUIRED] Step 2: Describe your environment

• Operating System version: macOS Mojave 10.14.2
• Browser version: Chrome 71.0.3578.98
• Firebase SDK version: 5.8.0
• Firebase Product: firestore

[REQUIRED] Describe the problem

An error message shows in the FIrebase Cloud Functions Logs when modifying a Firestore doc with a timestamp.

Steps to reproduce:

• In a Cloud Function, modify a Firestore doc with a timestamp property.
• See error:

@firebase/firestore: Firestore (5.8.0):
The timestampsInSnapshots setting now defaults to true and you no
longer need to explicitly set it. In a future release, the setting
will be removed entirely and so it is recommended that you remove it
from your firestore.settings() call now.

• Remove the explicit setting of timestampsInSnapshots from your codebase.
• In a Cloud Function, modify a Firestore doc with a timestamp property.
• See different error:

The behavior for Date objects stored in Firestore is going to change
AND YOUR APP MAY BREAK.
To hide this warning and ensure your app does not break, you need to add the
following code to your app before calling any other Cloud Firestore methods:

  const firestore = new Firestore();
  const settings = {/* your settings... */ timestampsInSnapshots: true};
  firestore.settings(settings);

With this change, timestamps stored in Cloud Firestore will be read back as
Firebase Timestamp objects instead of as system Date objects. So you will also
need to update code expecting a Date to instead expect a Timestamp. For example:

  // Old:
  const date = snapshot.get('created_at');
  // New:
  const timestamp = snapshot.get('created_at');
  const date = timestamp.toDate();

Please audit all existing usages of Date when you enable the new behavior. In a
future release, the behavior will change to the new behavior, so if you do not
follow these steps, YOUR APP MAY BREAK.

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

This is what I would expect to see at this stage. @firebase/firestore (the JS SDK) has already stopped supporting timestampsInSnapshots option. But firebase-admin (the Admin SDK) still does. These 2 libs should not be mixed in general -- especially in a server-side environment such as Cloud Functions.

firebase-admin will also drop support for this setting in an upcoming release.

@surajgupta57, it is a pretty descriptive error. Just do what it says. Somewhere in your code you have firestore.settings({ timestampsInSnapshots: true });. That needs to be removed.

here is the code @surajgupta57

firestore.settings({ timestampsInSnapshots: true }); use this to solve your prob

[jeremyfrancis]

In react native. Would commend out the line where the issue was and then another error showed up. Something at the core is wrong.
