Resolution:
During creation of service assembly through Business studio, if you specified description in multiple lines at Service Assembly Editor then it will throw below error during deployment

So to resolve this error you need to just avoid specifying description in multiple lines.

During deployment, service assembly giving an error “invalid header field”
