ispconfig 3.2.1 - acme.sh - dns

Hi there,
I'm currently transferring my old server to a new one.
On my old Server I used acme.sh with the DNS validation for letsencrypt and it worked like a charm. (Old is Debian jessie with ispconfig 3.1.xx / new is Buster with ispconfig 3.2.1)
On the old server the Acme DNS script connects via a remote user to ispconfig and adds / removes the txt challenge without any problem. On 3.2.1 I always get the error Message
{"code":"remote_fault","message":"Incorrect integer value: '' for column `dbispconfig`.`dns_rr`.`sys_userid` at row 1 INSERT INTO `dns_rr` (`server_id`, `zone`, `name`, `type`, `data`, `ttl`, `active`, `stamp`, `serial`, `sys_userid`, `sys_groupid`, `sys_perm_user`, `sys_perm_group`, `sys_perm_other`) VALUES ('1', '3', '_acme-challenge.some.domain.', 'txt', 'SOME-KEY', '3600', 'y', '2020-12-08 13:26:35', '1607430395', '', '', 'riud', 'riud', '')","response":false}

I then tried to use curl to try it on my own and it worked on the old server but on the new I've got the same Error Message.
Example: curl --header "Content-Type: application/json" --insecure --request POST --data '{"session_id":"XXX","client_id":"3","params":{"server_id":"1","zone":"8","name":"_acme-challenge.XXX.XXX.","type":"txt","data":"SOMEDATA","aux":"0","ttl":"3600","active":"y","stamp":"2020-12-08 13:26:35","serial":"1607430395"},"update_serial":true}' https://localhost:8080/remote/json.php?dns_txt_add

Any Idea what's going wrong?

Thanks!

 

thanks - I found the bug... It's like till said - I used the wrong client_id - on the new one there are fewer clients defined and thats why my old script didn't work... you shall not hardcode ids
