Cannot log errors from Plotly into error tracking service

[sporto]

Plotly logs some errors using its own logger:

https://github.com/plotly/plotly.js/blob/master/src/lib/loggers.js

This uses console.error. I understand that the console has its own exception handling that is not part of the page.

So an error tracking service like rollbar doesn't catch this and thus the error is not logged.

We would like to see those errors in Rollbar so we can investigate them.
Thanks

Hello @sporto and thank you for your interest in plotly.js!

Is my understanding correct that Rollbar would work if an ErrorEvent was fired in the following function: (

plotly.js/src/lib/loggers.js

Line 47 in c922c61

loggers.error = function() {

If so, it would be a pretty small change. I could submit a PR for it!

I'm unsure. I tried something like this in the console

var error = new ErrorEvent('Oh no', {
    error : new Error('ERROR'),
    message : 'Some message',
    lineno : 402,
    filename : 'index.html'
});

var target = document.getElementsByTagName("body")[0]

target.dispatchEvent(error)

Nothing was logged in Rollbar

I understand that the console has its own exception handling that is not part of the page.

Console errors should be part of the page if you call Plotly.setPlotConfig({logging: 2}) somewhere before your plot call.

.... which is info our doc pages probably lack at the moment. Thanks for writing in.

We added Plotly.setPlotConfig({logging: 2}) a few days ago. I'm still seeing the error in the console e.g.

ERROR: TypeError: Cannot read property 'fillcolor' of undefined
    at SVGPathElement.<anonymous> (plotly-basic.js:19501)

But we can't see anything in rollbar yet. So unfortunatelly logging: 2 hasn't done any difference.

Hi - this issue has been sitting for a while, so as part of our effort to tidy up our public repositories I'm going to close it. If it's still a concern, we'd be grateful if you could open a new issue (with a short reproducible example if appropriate) so that we can add it to our stack. Cheers - @gvwilson
