after hashing  
your are signing the XML & insert sign & Qr

when you do this any space added or removed will cause this error  
so as advice “if you don’t discover the error” remove spaces from your xml  
something like " …\</cac:Item\>cac:Price\<cbc:PriceAmount currencyID=“SAR”\>0\</cbc:PriceAmount\>cbc:BaseQuantity1\</cbc:BaseQuantity\>\</cac:Price\>\</cac:InvoiceLine\>"  
and try again
