Looks like you didn't configure Dovecot for use of the IMAP METADATA 
extension. That is a prerequisite for providing IMAPSIEVE support to 
your users.

https://wiki.dovecot.org/ImapMetadata

The main missing configuration is the mail_attribute_dict setting.

The error message you got was very unhelpful. That is fixed now:
