Problem editing replication tasks

[VulcanRidr]

Having an issue with a PULL replication task. The source machines are FreeBSD 12.1-RELEASE-p10, one a laptop with a single pool, and the other a desktop with two pools. One on a mirrored pair of SSDs and the other on a mirrored pair of spinning rust. I started by setting up a replication task for the laptop.

The destination machine is a FreeNAS running 11.3u5. I created the SSH connections, set up the source datasets to send, and got it all set up. Clicked save. I then noticed that the name of the task was based on the replication source and target. So I opened the pulldown (> on the right) and changed the name. When I clicked Save, I got the following error:

report_problem Error
[large_block] null not allowed

raise Error(self.name, 'null not allowed')
middlewared.schema.Error: [large_block] null not allowed

Has anyone seen this behavior before? Is there a fix/workaround for it?

Thanks,

I'm seeing the exact same error. I first encountered it while creating a new replication task but I just noticed that I can't edit any of my existing tasks. It seems to be complaining about the "Allow blocks larger than 128KB" setting.

Looks like a known bug. Rolling back to U4 is the recommendation and it appears a fix has already been submitted to the code base for the next service release.

If I'm on a machine that was a fresh install, what's the right way to downgrade--save the config, install old version, restore config? Is anything lost, like ssh keys?
