Backend

Describe the bug
A clear and concise description of what the bug is.

When doing a patch to the server with

from_entity: Optional[DashboardDataModel] = self.metadata.get_by_name(
                entity=DashboardDataModel,
                fqn=f"{self.config.serviceName}.model.MY_MODEL_NAME",
)

to_entity: DashboardDataModel = deepcopy(from_entity)
to_entity.sql.root = "updated sql !"

self.metadata.patch(
     entity=DashboardDataModel,
     source=from_entity,
     destination=to_entity,
)

It does not update the entity in OMD. The response from patch contains same old sql value.
