What is the problem you are having with rclone?

I'm trying to run the following command: rclone config create b2remote b2 but I'm getting the error:
failed to authorize account: failed to authenticate: This request is not currently supported on API version number 1 (400 bad_request)

What is your rclone version (output from rclone version)

v1.69.3-DEV

Which OS you are using and how many bits (e.g. Windows 7, 64 bit)

alpine amd64

Which cloud storage system are you using? (e.g. Google Drive)

b2 backblaze

The command you were trying to run (e.g. rclone copy /tmp remote:tmp)

rclone -vv config create b2remote b2 account="myacc" key="mykey" --non-interactive

A log from the command with the -vv flag (e.g. output from rclone -vv copy /tmp remote:tmp)
