Feel free to use 11.1-dev in the webpack branch, everything works correctly there.
I'm not sure what exactly is wrong with 11.1.0, since it also doesn't throw an error. It just stops at identifying with the gateway. So this needs a bit more investigation.

11.1-dev works correctly though.

[yuta0801]

Thank you.

I tried discord.11.1-dev.js and discord.11.1-dev.min.js.

Both are Client.user is null.
and min.js get error Cannot read property 'handle' of undefined.

Uncaught TypeError: Cannot read property 'handle' of undefined
    at s.handle (discord.11.1-dev.min.js:1)
    at r.handle (discord.11.1-dev.min.js:1)
    at h.onPacket (discord.11.1-dev.min.js:1)
    at h.onMessage (discord.11.1-dev.min.js:1)

What browser are you using?

[yuta0801]

The latest version Google Chrome

[iCrawl]

I tested this on Chrome Version 62.0.3192.0 (Official Build) dev (64-bit) dev
and Version 60.0.3112.113 (Official Build) (64-bit) stable

And it works perfectly fine with discord.11.1-dev.min.js

Can I see your code?

[yuta0801]

Sorry, I forgot to await ready event.

The original issue was solved,
but I confirmed Cannot read property 'handle' of undefined error in min.js.

Uncaught TypeError: Cannot read property 'handle' of undefined
    at r.handle (discord.11.1-dev.min.js:1)
    at r.handle (discord.11.1-dev.min.js:1)
    at h.onPacket (discord.11.1-dev.min.js:1)
    at h.onMessage (discord.11.1-dev.min.js:1)

This seems to be an issue with the minified file.

I cannot reproduce this on 11.1-dev though. Only on 11.1-dev.min

[yuta0801]

Noted with thanks.

[iCrawl]

This should be finally fixed now. All minified webpacks have been updated 👍

still happening on discord.js 11.3.0

This is happening on 11.4.2:

[iCrawl]

Yes, this most likely won't be fixed until we release a new version.

Use https://github.com/discordjs/discord.js/blob/webpack/discord.11.4-dev.min.js instead.

It is non-breaking to the current stable release.

I'm hitting this same issue on 11.5.1 - all prod builds by webpack fail and I have to use a development bundle

[ScarletMetal]

so is there any progress on this issue? I too encountered this issue on 11.5.1

[edusperoni]

As a workaround, set keep_classnames: true in your terser options.

new TerserPlugin({
    terserOptions: {
        keep_classnames: true
    }
})

Just came across this issue trying to run on a production build, development works fine, version 12.2.0.
Workaround mentioned above had no effect.
