Error: "Cannot read property 'Latency' of undefined"?

[seanvree]

Hey man!

Thanks for doing this!

So, I'm running this on windows...(I'm no noob) and I've modified everything to work, and the dashboard launches but I just get the spinning graphic,

If I inspect the browser element,

I'm getting this error:

dygraph-combined.js:3 Uncaught TypeError: Cannot read property 'Latency' of undefined
    at t.getPropertiesForSeries (dygraph-combined.js:3)
    at Function.t.generateLegendHTML (dygraph-combined.js:5)
    at t.deselect (dygraph-combined.js:5)
    at t.cascadeEvents_ (dygraph-combined.js:2)
    at t.clearSelection (dygraph-combined.js:3)
    at t.mouseOut_ (dygraph-combined.js:3)
    at mouseOutHandler_ (dygraph-combined.js:2)

Any ideas?

Hello,

sorry for the delay, didn't see the mail.

Does the script actually get the wanted json? Seems an undefined object is passed to dygraph.

@cjeanneret - No prob!

I'm not sure actually. How do I check?

[cjeanneret]

you can check the network traffic.

Also, it might be good to get the full error - in the partial output you pasted, we only get the dygraph issue, but not where in the custom script.js it happens.
There are some calls to the dygraph part, of course, and it might be good to know where it crashes.

Cheers,
