Unable to start debugging : The value of miDebuggerPath is invalid

I recently started working on vscode. I wanted to debug my C code. But the moment I am launching the debugger getting Error : Unable to start debugging. The value of miDebuggerPath is invalid.

I have my gdb installed on wsl . It's path is /usr/bin/gdb. I have copied same path to launch.json in miDebuggerPath.

Here is my launch.json :

{

"version": "0.2.0",
"configurations": [


    {
        "name": "(gdb) Launch",
        "type": "cppdbg",
        "request": "launch",
        "program": "${workspaceFolder}/bin/main",
        "args": [],
        "stopAtEntry": false,
        "cwd": "${workspaceFolder}",
        "environment": [],
        "externalConsole": true,
        "MIMode": "gdb",
        "miDebuggerPath": "/usr/bin/gdb",
        "setupCommands": [
            {
                "description": "Enable pretty-printing for gdb",
                "text": "-enable-pretty-printing",
                "ignoreFailures": true
            }
        ]
    }
]

}

It should not throw the error and I should able to launch my debugger.
