Invoice and Xml does not match in sandbox api

Clearance and Reporting
1

I am currently implementing the ZATCA to my project, and I am facing an issue while calling clearance API in B2B case, error message is :

    "errorMessages": \[

        {

            "type": "ERROR",

            "code": "invalid-invoice-hash",

            "category": "INVOICE_HASHING_ERRORS",

            "message": "The invoice hash API body does not match the (calculated) Hash of the XML",

            "status": "ERROR"

        }

    \],

how to solve this I am using sandbox api tesing and dot net core api,

xml :
