doveadm http api expunge call

Hi all,

i'm start porting some of my maintenance scripts from doveadm cli to doveadm http api.

I stumble over the doveadm expunge call. The response doesn't contain any additional output but the generic doveadmresponse object without any additional information. The list is always empty wether the expunge has expunged some emails or not: [['doveadmResponse', [], 'tag1']]

Other then the cli command wich outputs a list of the mails that were expunged.

Is this a bug?

Best regards, Tim
