SoapUI running in Docker Container throwing java.lang.NoSuchMethodException: Unknown property 'host'

I was able to execute the soapUI script successfully via docker. But in log I am getting the below error. It is not actually causing the step to fail but it happens for every request I make. I was not able to find a reason or fix for this. Could you please help me? I am running SoapUI 5.5.0 open source version in Openjdk8 environment.
