Do you see this error while testing web service from SICF (Transaction Code)?
For me a small change in SOAMANAGER solved this error, go to SOAMANAGER –> Web Service Configuration
Search for your web service
Select this Web Service –> Click on Pencil Icon
Go to Transport Settings Tab :
Option : Make Local Call –> From drop down select
No make a Test again in Tcode – SICF, you will not see the error again, there will be a blank page. There may be other reason too but for me, it worked. My system information:
I hope it will help someone to get rid of this error.
