Child table get blank on save

[Francisco_Buendia]

Hello team,

I’m having some issues with a couple of custom scripts that always worked fine on v12. First:

frappe.ui.form.on("Delivery Note",{
    srv_inhumacion: function(frm) {
		frm.trigger("carta_ubicacion");
	},
	validate: function(frm) {
		frm.trigger("carta_ubicacion");
	},
    carta_ubicacion: function(frm){
        frm.clear_table('carta_ubicacion_referencia');
        frappe.call({
            method:"frappe.client.get_list",
            args:{
                doctype:"Sales Invoice Item",
                fields:["item_code", "item_name", "servicio", "description", "qty", "uom", "warehouse", "batch_no", "serial_no"],
                parent: "Sales Invoice",
                filters: [
                    ["parent", "=", frm.doc.sales_invoice]
                    ],
            },
            callback: function (r) {
                console.log(r.message);
                if (r.message) {
                    $.each(r.message, function(index, row) {
                        var d = frm.add_child("carta_ubicacion_referencia");
                        d.item_code = row.item_code;
                        d.item_name = row.item_name;
                        d.servicio = row.servicio;
                        d.description = row.description;
                        d.qty = row.qty;
                        d.uom = row.uom;
                        d.warehouse = row.warehouse;
                        d.batch_no = row.batch_no;
                        d.serial_no = row.serial_no;
                        d.item_code = row.item_code;
                    });
                }
                frm.refresh_field("carta_ubicacion_referencia");
            }
		});
	}
});

And also used to work using this second script:

frappe.ui.form.on("Delivery Note", {
	srv_inhumacion: function(frm) {
		frm.trigger("carta_ubicacion");
	},
	carta_ubicacion: function(frm) {
        if(frm.doc.srv_inhumacion && frm.doc.sales_invoice){
            frm.clear_table("carta_ubicacion_referencia");
            frappe.model.with_doc("Sales Invoice", frm.doc.sales_invoice, function () {
                var tabletransfer = frappe.model.get_doc("Sales Invoice", frm.doc.sales_invoice);
                frm.set_value('si_naming_series', tabletransfer.si_naming_series);
                $.each(tabletransfer.items, function (index, row) {
                    var d = frm.add_child("carta_ubicacion_referencia");
                    d.item_code = row.item_code;
                    d.item_name = row.item_name;
                    d.servicio = row.servicio;
                    d.description = row.description;
                    d.qty = row.qty;
                    d.uom = row.uom;
                    d.warehouse = row.warehouse;
                    d.batch_no = row.batch_no;
                    d.serial_no = row.serial_no;
                    frm.refresh_field("carta_ubicacion_referencia");
                    frm.refresh();
                });
            });
        }
        else {
            frm.set_value("sales_invoice", "");
            frm.set_value("funeraria", "");
            frm.set_value("use_stock", "");
            frm.clear_table("carta_ubicacion_referencia");
        }
    },
});

Both worked fine on v12. But you’ll see that now apparently the table seems to get blank on save and I’m mean apparently because I if clic on print, data appears on print format. I have to refresh to see again the data on the table.

This error appears on console when first clic on srv_inhumacion to load data on table

Uncaught TypeError: Cannot read property 'startsWith' of null

        at HTMLBodyElement.dispatch (jquery.min.js:3)
        at HTMLBodyElement.r.handle (jquery.min.js:3)

When clic on save, these two appears on console

Any hint to solve would be much appreciated!

The last two errors:

Any thoughts?

Did you get any solution yet?
I am facing the same issue in v13 also.

[Francisco_Buendia]

No, not any at all.
