iCloud Sync Error for select folders

Are there any related issues?

Not that I can see

Bug?

Do you have any third-party plugins installed? If so, which ones?

No

Is the issue related to a specific email provider (Gmail, Exchange, etc.)?

It looks like mostly an iCloud issue, but my G Suite trash folder is also struggling to sync.

Is the issue reproducible with a particular attachment, message, signature, etc?

Not that I'm aware of.

Description

Basically a few folders from my iCloud email are not syncing at all (along with the trash folder from my G Suite). Running Mail with Debug Flags shows only one error, and the popup saying "Encountered an error while syncing" is permanently in place. The error reads:

/Applications/Nylas Mail.app/Contents/Resources/app.asar/node_modules/fbjs/lib/warning.js:36 Warning: Each child in an array or iterator should have a unique "key" prop. Check the render method of SyncActivity. See https://fb.me/react-warning-keys for more information.

There's no correlation between the folders that would indicate it's an account issue, so I can't work out why this isn't working. I also have 2FA enabled, using an app password if that helps at all.

Maybe related...

I keep getting "Encountered an error while syncing <email@me.com>". Oddly enough, I have two iCloud accounts - one an older one that I still use with @me.com and a newer one. The older one is the one getting this error.

Nothing in Developer Console when running Nylas Mail with Debug Flags apart from a possible memory leak in EventEmitter.

I have the same iCloud issue as @skyesofrock
Folders have synced (i.e. i can see the folders names) but nothing inside any of them.
Tried to pull debug logs but i don't see any actual errors 👎

thanks for the details!I think the error you are seeing must be related to this one #3198 (comment)

Just resolved the iCloud sync issue by going into iCloud.com and deleting some old folders (Mailbox, Mailpilot, Airmail). My hunch is that nested folders (Mailbox/Foo) might have been an issue...

this should be fixed on 1.0.26 which was released today! Thanks for your patience!

Can confirm it's working, thanks for the fix!
