node-inspector: Undefined `ref` property

node-inspector version: 0.12.8 node version: 6.9.1 OS: Windows 10 x64

if (!NM.length)
   error = new Error('No NativeModule in target scope');

cb(error, NM[0].ref);

if NM.length is zero, NM[0] is undefined and node-inspector crashes with TypeError: Cannot read property 'ref' of undefined.

About this issue

I also get this error:

if (!NM.length)
   error = new Error('No NativeModule in target scope');

cb(error, NM[0].ref);

temporary change :

if (!NM.length){
    error = new Error('No NativeModule in target scope');
    return cb(error);
}

cb(error, NM[0].ref);

same problem here on windows 10
