Total Invoice Ammount is 0 after Scanning QR Code

When i Scan the QR code for Credit Code invoice after getting Signed from Zatca
i got 0 in the Total invoice Ammount?
is there anything i am missing in my XML or anywhere Else?

Who knows, if you don’t share your XML Invoice and QRCode Image here

Amount due for payment (BT-115) = Invoice total amount with VAT (BT-112) -Pre-Paid amount (BT-113) + Rounding amount (BT-114).

this is the Warning i got for the invooice

This is my invoice
is it due to that my rounding ammount is also equals to the ammount paiable??

This should be 157.50

Can you please Tell me what is Rounding Ammount Actually?
