Were you able to solve this? here is how i would do it

frappe.ui.form.on(“Journal Entry”,
{
amount:function(frm) {
// accounts is the name for Journal Entry Account
$.each(frm.doc.accounts || , function(i, d) {
if(!d.debit_in_account_currency) d.debit_in_account_currency = frm.doc.amount;
});
refresh_field(“accounts”);
},
});
