missing a fetch polyfill?

[chriddyp]

I've tested this in IE11 myself, so I'm surprised by this bug report, but perhaps we're missing a fetch polyfill: https://community.plot.ly/t/on-ie11-getting-error-script5009-fetch-is-undefined/14445

@valentijnnieman - could you look into this one?

[valentijnnieman]

@chriddyp Can you invite me to Browserstack?

I think we might have lost the whatwg-fetch polyfill with the webpack config changes, it needs to be added to the entry in webpack.config.js

[valentijnnieman]

I added it back in in #86

[chriddyp]

OK cool, let's get #86 merged and released ASAP then

Hi, not sure the status of this issue, but I uploaded to dash-render 0.14.2 and now I'm getting a new error in IE:

[object Error]{@@hasInstance: undefined, @@isConcatSpreadable: undefined, @@iterator: undefined, @@match: undefined, @@replace: undefined, @@search: undefined, @@species: undefined, @@split: undefined, @@toPrimitive: undefined, @@toStringTag: undefined, @@unscopables: undefined, description: "Object does...", message: "Object does...", name: "TypeError", number: -2146827850, stack: "TypeError: ..."}

Anyone else getting this error?

Here is the stacktrace as well. Hopefully this will be helpful in addition to the top error message.

Yikes, it looks like we're missing a few polyfills here. @valentijnnieman et al, we should just include the babel polyfill: https://babeljs.io/docs/en/babel-polyfill I think

[chriddyp]

I'll look into adding this now so that we can get out the fix asap

@mbkupfer - New release at pip install dash-renderer==0.14.3. Could you try it out?
