The Response Message without Content-Type Header

[ideateknoloji]

When i try to send an invoice from Difi's test endpoint to my server application, the application returns a response message without Content-Type header in response. But other case (when i send a message from my client application which uses as2-peppol-client) no problems occur.

I share my log files above:

tomcat-stdout.log

[2018-11-09T14:42:09,358] [PEPPOL-AS2-SERVER] [WARN ] [https-jsse-nio-443-exec-9] No content type on HTTP 200 response to POST 'https://peppoltest.visionplus.com.tr/as2-peppol-server/as2' -- com.helger.xservlet.filter.XServletFilterConsistency.checkContentType(XServletFilterConsistency.java:141)

I need to check the RFC if Content-Type on ACK is mandatory or not
