Update DOB via HDL

Summary:

Hello - I'm trying to update the DOB of some existing employees using HDL. I'm only passing the Worker metadata, but it is throwing the error "You must provide only one parent record Worker and it must start on the earliest effective start date and not have an end date."

Below is the HDL I have tried to load.

METADATA|Worker|PersonNumber|PersonId|EffectiveStartDate|EffectiveEndDate|DateOfBirth|StartDate|ActionCode
MERGE|Worker|007730|300000002057436|2025/02/03||1980/01/15|2016/01/04|ASG_CHANGE

Is there any other metadata I need to add in my hdl file to do this activity? In the front-end, I can update the DOB with no issue.
