Catchable Fatal Error: Object of class

[ghost]

Good day,

Please your help!

I built a Web service, but when I execute it. I got the next issue:

http://localhost:8000/app_dev.php/ws/AplicationService?wsdl

Catchable Fatal Error: Object of class Symfony\Component\Config\ConfigCache could not be converted to string
