No snapshots to send for replication task

[domo]

Hello,
I have 4 NAS 'AP' that replicate to on 'AS' and 'BP' that replicate to 'BS'. on both AP and BP i have configured the replication task, they are identical.
The replica AP->AS works fine on the contrary the replica BP->BS give me the issue:

and no dataset nor snapshot are created on 'BS'. I have recreated the task more and more times but no way to replicate the datasets.
Where can i look for reason of this issue? Is it a bug?
Thanks.

No snapshots to send for replication task 'task_1' on dataset 'Pool0'

Are you sure you have any snapshots on BP ? How is your regular snapshot task on it ?

Hi Heracles,
thanks for your reply, yes
here the job and the snapshot list.

Are those snapshots empty?

 

[domo]

Yes, some are empty, but i didi expect that the replication task did replicate the data, on the contrary at destination 'BS' the Pool is empty, the datasets didn't copied.

I have configured the same task into the target Truenas 'BS' with remote source Pool. The replication started and copied all snapshot regulary. This is the demostration that the snapshot are consistent and for some issue or a bug the replication task from the source 'BP' doesn't work.
