unable to unmarshal: wappalyzer schema definition file changed

[francisco-sec]

I installed your tool like described in the README (in Arch Linux) and it keeps giving this error below:

$ go run cmd/webanalyze/main.go -host https://host/path/ 
2017/08/10 16:24:18 error initializing: json: cannot unmarshal number into Go struct field App.cats of type string

Is this normal? After the previous error the execution seems to proceed but hang.

Thanks for the notice. It looks like the schema of the apps.json file from webanalyze changed again. I will check this.

So the problem is that wappalyzer is not very .. strict on their apps.json schema. Have a look at how the usually define their categories, for example:

"cats": [
    "20",
    "51"
],

And now look at this:

"cats": [
    1
],

This fails to unmarshal, because I am expecting a string, and not a number. To fix this you can do this by hand (change 1 to "1"). I will also prepare a PR for the wappalyzer repository.

Update: You can track the PR here.

Many thanks you for your quick answer. I made that change in my local apps.json and it works now.
