SOAP on Business Central Saas

Hi experts,

I am trying to write a codeunit in BC SaaS to receive the following request:

<s:Body>
<saveCustVend xmlns="http://tempuri.org">
<DC xmlns:d4p1="http://schemas.datacontract.org/2004/07/Dynamics" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<d4p1:No>1</d4p1:No>
<d4p1:Name>Test</d4p1:Name>
</DC>
</saveCustVend>
</s:Body>

My codeunit looks like this:

codeunit 50100 "CustVendWebService"
{
    [ServiceEnabled]
    procedure saveCustVend(var DC: Text[100240]): Text
    var
        CustVendRecord: Record "Customer";
        AccountNum: Text[20];
        Name: Text[100];
 
    begin
 
        AccountNum := GetValueFromXML(DC, '<d4p1:AccountNum>', '</d4p1:AccountNum>');
        Name := GetValueFromXML(DC, '<d4p1:Name>', '</d4p1:Name>');
        CustVendRecord.Init();
        CustVendRecord."No." := AccountNum;
        CustVendRecord."Name" := Name;
        CustVendRecord.Insert();
        MESSAGE('Customer record inserted: %1', AccountNum);
    end;
    local procedure GetValueFromXML(XMLText: Text; StartTag: Text; EndTag: Text): Text
    var
        StartPos: Integer;
        EndPos: Integer;
        Value: Text;
        FullStartTag: Text;
    begin
        FullStartTag := StartTag;
        StartPos := StrPos(XMLText, FullStartTag);
        EndPos := StrPos(XMLText, EndTag);
        if (StartPos > 0) and (EndPos > StartPos) then
            Value := CopyStr(XMLText, StartPos + StrLen(FullStartTag), EndPos - StartPos - StrLen(FullStartTag));
        exit(Value);
    end;
}
 
I have published web service, and when I test it in postman, I get this error:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Body>
        <s:Fault>
            <faultcode xmlns:a="urn:microsoft-dynamics-schemas/error">a:Microsoft.Dynamics.Nav.Service.SOAP.ServiceBrokerException</faultcode>
