SOAP Null response if HTTP Status 500 (Soap multipart)

Không có tệp mã nguồn hoặc bài kiểm thử nào được nêu. Hãy bắt đầu bằng cách tái hiện request của SoapClient trong PHP 8.3.13 với một phản hồi SOAP multipart HTTP 500 và so sánh với __getLastResponse(); được xem là hoàn tất khi phần body của SOAP fault được trả về có thể truy cập thay vì NULL.

Description

I've created a soap request with integrated soapclient. As long as the request contains only valid data everything works fine.
But as soon as the request fails, the server returns HTTP Status 500 and __getLastResponse is NULL, even if data is returned. Below you can find the SOAP request and the expected answer based on SOAP UI request

<?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://soap.elgaad.client.chipkarte.at"><SOAP-ENV:Body><ns1:medikationslisteAbrufen><ns1:dialogId>***</ns1:dialogId><ns1:svNummer>***</ns1:svNummer></ns1:medikationslisteAbrufen></SOAP-ENV:Body></SOAP-ENV:Envelope>

Resulted in this output:

NULL

But I expected this output instead (tested with SOAP UI):
