Unable to debug C on VS Code using gdb on Windows Subsystem for Linux

I am using VS Code to debug 'C' code using Windows Subsystem for linux. I basically want to compile the 'C' code using a linux based compiler for a Operating System's course. I have set the default terminal to 'WSL' on Visual Studio Code. On clicking the debug button I am getting the below error 'Unable to start debugging. The value of miDebuggerPath is invalid' I verified that 'gdb' is installed in the Windows Subsystem for Linux and its executable (ELF File) is present in '/usr/bin/gdb' location

This is m launch.json

            ],
            //"preLaunchTask": "Compile C Ubuntu"
        }
    ]
}

Any direction will be helpful :)
