AAA HTTP server with custom body

Hello,

maybe someone had this problem before and used this object with success.

I have HTTP API that is supposed to send sms with OTP. I have this implemented over Microsoft NPS but now i'm trying to drop it and replace it with F5 to generate the tokens.

I am supposed to send POST with something like this:

<sendSms xmlns="http://link.whatever">

 <sender>

  <static>

<staticId>myname</staticId> 

<billingCcn>myID</billingCcn> 

  </static>

 </sender>

 <recipient>

<msisdn>phonenumeber</msisdn>

 </recipient>

 <text>stufftoputinthere</text>

</sendSms>

and it works fine from postman. Now i inserted that into HTTP Server like this:

and put it into the access rule. Event is triggered but it never works. So i went deeper into troubleshooting and sniffed the traffic. My HTTP request from F5 comes to the web server as something meaningless, there are no headers, no body, just Data with some random stuff in it. Any ideas?
