SOAP Error - Error on Execution

SOAP Error - Error on Execution

Hey everybody,

I try a SOAP-Post Request, but everytime I get this:

Result:

Error on Execution

Error details:

Execution Failed

Error due to - 'Internal Exception' Line:(39)

The script is working on Postman and SoapUI, but not on Zoho Creator.
This is my sourcecode:

requestBody = "";

requestBody = requestBody + "<soapenv:Envelope ";

requestBody = requestBody + "xmlns:soapenv=\" https://schemas.xmlsoap.org/soap/envelope/\" ";

requestBody = requestBody + "xmlns:rep=\" https:// XXXXXX/soap.php/soap/report\">";

requestBody = requestBody + "<soapenv:Header/>";

requestBody = requestBody + "<soapenv:Body>";

requestBody = requestBody + "<rep:getAll>";

requestBody = requestBody + "<mandator_id>4</mandator_id>";

requestBody = requestBody + "</rep:getAll>";

requestBody = requestBody + "</soapenv:Body>";

requestBody = requestBody + "</soapenv:Envelope>";

password = "XXXXXXXX";

username = "XXXXXXXX";

baseEncoded = zoho.encryption.base64Encode(username + ":" + password);

requestHeader = Map();

requestHeader.put("Authorization","Basic " + baseEncoded);

requestHeader.put("Content-Type","text/xml");

requestHeader.put("SOAPAction","\" https://XXXXXX/soap.php/soap/report#getAll\"");

apiResponse = postUrl(" https:// XXXXXX/soap.php/soap/report",requestBody,requestHeader,false);

return apiResponse;

What's wrong?
