SAP MII HTTP Post uncaught error

Hi Dear,

I'm trying to send data to a http post, I did the same procedure using the SOAPUI software and worked fine, but with SAP MII HTTP Post is returned an error, and without any detail.

What can I be doing wrong?

Using SoapUI: Works fine!

Using SAP MII 15.2 SP03 Patch 8:

Thank you for your attention.

Best Regards,
