Timeout waiting for initial Debugger Protocol connection

Failed to generate report {"stack":"TypeError: Cannot read property 'replace' of undefined

i guess generateReport is getting undefined data.

[paulirish]

seems more like a lighthouse problem, but at least you can assert there's data returned before going into createReport, etc.

[paulirish]

also getting this:

garie-lighthouse_1  | error: Failed to save lighthouse data for https://www.paulirish.com {"stack":"TypeError: Cannot convert undefined or null to object
    at Function.keys (<anonymous>)
    at saveData (/usr/src/garie-lighthouse/src/influx/index.js:32:25)

    at process._tickCallback (internal/process/next_tick.js:188:7)","timestamp":"2018-10-02T17:33:16.156Z"}

I suppose it's the same root issue.

[paulirish]

Ah yes the root issue is likely this one:

Failed to get data for https://www.paulirish.com {"stack":"Error: Timeout waiting for initial Debugger Protocol connection.

Hey @paulirish !

Thanks for raising the issue, Are you running the garie-v2 branch?

I'll try and replicate this locally and will take a look 👍 thanks for raising it.

[paulirish]

Are you running the garie-v2 branch?
Yup i am. updated to master as of 5 hours ago.

I'm just running garie against paulirish.com every 1 minute. :)

I think this happened while my machine was sleeping. Though it didnt happen just now as I stepped away for 45 minutes. Probably wont be easy to reproduce, though I suspect Chrome isn't launching successfully.

[boyney123]

but at least you can assert there's data returned before going into createReport, etc.

Yeah good idea, il have a look at that.

Yeah il try and change my settings to match yours and see if I can replicate it too.

[paulirish]

@boyney123 you can reproduce part of this by just disconnnecting from WiFi. :)
