Your solution didn't match the expected output.
attempted to install this via
npm --global install bug-clinic
and install results looked good except for
C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Microsoft.CppBuild.targets(297,5): warning MSB8003: Could not find WindowsSDKDir variable from the registry. TargetFrameworkVersion or PlatformToolset may be set to an invalid version number. C:\Users\MYUSERNAME\AppData\Roaming\npm\node_modules\bug-clinic\node_modules\bunyan\node_modules\dtrace-provider
build\DTraceProviderStub.vcxproj]
I tried anyways to run
bug-clinic
and the response was:
C:> bug-clinic run
C:\Users\MYUSERNAME\AppData\Roaming\npm\node_modules\bug-clinic\node_modules\mkdirp\index.js:89
throw err0;

RangeError: Maximum call stack size exceeded
If anyone could help me figure out if i need to install some dependency or something, I would be very appreciative. I am really interested in this as I am new to js (background is in python, powershell, C#) and im really looking forward to upping my debug skills.
I downloaded the solution.js from problems/stacktraces. But when I try the
bug-clinic run solution.js
I get the following error:

Why is it?
In the README it states "please note this is only about 2/3 complete". However the last commit was on Nov 1, 2014. Is there more work planned, or is the tutorial complete?
Why ?
res.on("end", function (e) {
console.error("done!");
});
Why is this not ok?
res.on("end", function (e) {
console.log("done!");
});
I'm doing bugclinic challanges, but I couldn't find any errors in scan exercice.
The proposed server and client files pass verify with no errors.
Although I have understood the concept of NODE_DEBUG I tought maybe I'm missing something here.
Is this a bug or I'm really missing something ?
For instance, perhaps it should mention that the server should run on port 8080... I noticed a few other things to : Would you be interested in a patch?
Regardless of whether I fix the isGreaterThanZero function, I see this weird error.

Thanks for the workshop, but when I run the scripts the blinking results distract a lot! no offense ;)
Students are using 8.10.0 at Nodeschool Baltimore and they are unable to finish due to the Traces exercise use of deprecated Node module domain
