'You must provide a value for the OwnerPersonId attribute.' When update employee bank account owner

Hi All,

I have an external bank account which has 2 acccount owner. (Actually they are same person while rehire assign a new person number and account for him).
Now when GET his bank account via /fscmRestApi/resources/11.13.18.05/externalBankAccounts, It always return old PersonId.

I'd like to make it show the new person id, so I add a new account owner for the external bank account :
