1195212 - policies.jsm:692:0 throws an error in the Browser Console each time a sync is initiated

Status: RESOLVED DUPLICATE of bug 987091

(Firefox :: Sync, defect)

Description

[Andrei Vaida [:avaida]]

Attachment: sample sync log

Reproducible on:
* Nightly 43.0a1 (2015-08-16)
* Aurora 42.0a2 (2015-08-16)
* Firefox 41.0b1 (20150811185633)

Affected platforms:
* Windows 7 (x64)
* Windows 10 (x86)
* Mac OS X 10.10.4
* Ubuntu 14.04 (x86)

Steps to reproduce:
1. Launch Firefox.
2. Log into your Firefox Account.
3. Check the Browser Console.
4. Initiate a manual sync or add a new bookmark. Check the Browser Console again.

Expected result:
* The initial sync (after the first FxA login) is successful and no errors are thrown in the process.
* All the data from that FxA is successfully synced down to that profile.

Actual result:
* The data from the FxA in question is successfully synced down.
* The following error is thrown in the Browser Console by policies.jsm:692:0 each time a sync is initiated:
> Sync encountered an error - see about:sync-log for the log file.

Notes:
* I did _not_ notice this error in Firefox 40.0.2, but I wouldn't cross Fx40 out because there are different errors thrown there.
* I've attached a sample log from about:sync-log.
* It's also worth mentioning that this issue is reproducible with and without e10s.

Sorry for the delay.

There are 3 errors in that log:

> 1439800208451	Sync.Store.Bookmarks	ERROR	creating livemark failed: Error: no item found for the given itemId
(the above actually repeats a number of times) - I suspect we've fixed that, but certainly recent changes mean that specific error will be reported quite differently - so it's currently hard to action this, but if we see it in newer version we certainly want to know about it.

> 1439800208466	Sync.Engine.Bookmarks	ERROR	null

This has been fixed.

> 1439800199961	FirefoxAccounts	ERROR	Error updating FxA account info: Error: A different user signed in (resource://gre/modules/FxAccounts.jsm:155:29) JS Stack trace: 

This is bug 987091 - I'm going to dupe this bug to that.
