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 :

> ```auto
> "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 :
