KeyError: 'buckets' when using v4.4.1, v4.3.3 works fine

Upgraded b2 recently to v4.4.1 and getting the following error when trying to sync folders:

KeyError: 'buckets'

Downgrading to v4.3.3 resolves the issue.

@yury-tokpanov
b2 v4.4.x requires b2sdk 2.9.4.
Please, make sure you upgrade the sdk library alongside the CLI.
LMK if the issue still persists after upgrading both packages.

I'm having the same issue. I uninstalled and reinstalled via Homebrew. Looks like b2sdk is at 2.9.4 via Homebrew.

This appears to be a bug, we're investigating the cause.

In the meantime, a workaround is to remove local sqlite cache (the default location is ~/.b2_account_info) and reauthorize:

rm ~/.b2_account_info
b2 account authorize <applicationKeyId> <applicationKey>

Hi, running into this with the following call

env \
        B2_APPLICATION_KEY_ID="$1" \
        B2_APPLICATION_KEY="$2" \
        b2-wrapper sync \
        --exclude-regex "$ar_b2_default_exclude_regex" \
        $extra_args \
        "$3" "b2://$4"

EDIT

Where I get my account info with

backblaze-b2 account get

And store it locally.

My versions:

extra/python-b2sdk 2.10.0-1 (479.9 KiB 3.2 MiB) (Installed)
    Python module to access B2 cloud storage
aur/backblaze-b2 4.4.1-1 (+25 0.00) (Installed)
    Backblaze B2 Command Line Client

I have the same problem with B2SDK 2.10.1. Downgrading B2 to 4.3.3 resolves the issue.
