Validation error on cluster_name is empty

[DX]

Hi,

When trying to update the Worker Type for a cluster that is specific for a job, I get a validation error saying the cluster name is empty.
The name is present in the UI.
In json view, the attribute is set to empty string ("")
Swapping for a new cluster gives me the same error.
Creating a new Task with a new Cluster gives me the same error.
I could not find anything specific in the console logs.
I have Admin access and "Unrestricted cluster creation" entitlement.

@DX Is that job cluster/all purpose cluster that you are using for Jobs

Thanks @karthik_p for your time looking into this.

It's a job cluster.
I have the same error on all job cluster that I checked so far (5 out of ~20).
The cluster has nothing special about it that I can think of.
There are no GPUs, not a huge amount of workers, ...
