I don't know what is going on. This comes when I send a message. I was trying to use the webhook thingy. Without it works just fine. My config:

[{
        "nickname": "StackHub",
        "server": "irc.freenode.net",
        "discordToken": "XXX",
        "autoSendCommands": [
                ["PRIVMSG", "XXX", "Up"]
        ],
        "channelMapping": {
                "#questions": "##stackhub"
        },
        "format": {
                "commandPrelude": "Command sent by {$nickname}",
                "ircText": "<{$displayUsername}> {$text}",
                "urlAttachment": "<{$displayUsername}> {$attachmentURL}",
                "discord": "**<{$author}>** {$withMentions}",
                "webhookAvatarURL": "https://robohash.org/{$nickname}"
        },
        "ircNickColor": true,
        "ircNickColors": ["light_blue", "dark_blue", "light_red", "dark_red", "light_green", "dark_green", "magenta", "light_magenta", "orange", "yellow", "cyan", "light_cyan"],
        "parallelPingFix": true,
        "commandCharacters": ["!", "."],
        "ircStatusNotices": true,
        "webhooks": {
                "#questions": "https://discord.com/api/webhooks/XXX"
        }
}]

Hey! I can't seem to reproduce this issue locally when using webhooks.

Could you please provide this information so I can investigate further?

• Node + NPM versions (node --version && npm --version)
• discord-irc version (discord-irc --version, or if you built it from source, git rev-parse --short HEAD)
• The full log of the error (line numbers and the stack trace may be important!)

I'm also getting this error.

NPM version 5.8.0 Node version 10.24.0 discord-irc version 2.9.0

The error is exactly as shown:

$ discord-irc --config config.json
2021-05-09T11:37:00.770Z info: Connected to Discord
2021-05-09T11:37:01.577Z info: Connected to IRC
2021-05-09T11:37:10.747Z error: Object.entries(...).filter(...).flatMap is not a function

Ah, I see! I think that explains it: I googled a bit, and flatMap was added in Node 11, so it's not available in Node 10.

Node 10 recently went EOL, so I recommend upgrading your system node for most apps anyway, but in particular, due to our reliance on the discord.js library, we dropped support for old Node versions (6, 8 and 10) in version 2.9.0, in October 2020, which was necessary for some upcoming Discord API changes. We've got a notice in the README, but maybe it's not prominent enough:

Note: discord-irc requires Node.js version 12 or newer, as it depends on discord.js. Future versions may require newer Node.js versions, though we should support active releases.

Could you try upgrading your system Node version, and see if that helps?
