Hi all, I’m having an emergency issue with pipeline. I’m deleting some datasets in LDM and remove out_tables in database warehouse. The release brick works, but rollout brick failed. It throws an error

```E, [2023-01-13T173109.439170 #7] ERROR -- : Execution failed. Error: [

}

It cannot sync master workspace to client workspaces. Could you please help me to fix it asap?

Hi Nam, the rollout brick can’t synchronize projects because they have different data model. The solution will be to run the brick with additional parameter

synchronize_ldm

. More info about this parameter can be found here: Rollout Brick

Thanks Moises, the value of

synchronize_ldm

should be

diff_against_clients

, right?

You’re welcome. Yes, I believe so, although I’m not familiar with your LCM setup so please read thoroughly the description of all the values.

thanks so much, that value works for me 🙂
