MemberJoinedChannelEvent interface doesn't contain "enterprise" field

[valkirilov]

I’ve been playing with the member_joined_channel event and have noticed that the corresponding interface for this event might be outdated. Examining the payload of the event I received, I found the enterprise field, which contains the ID of the Slack organization, but it’s absent from the interface itself.

• node-slack-sdk/packages/types/src/events/member.ts

  Line 4 in 6c29b1b

  channel: string;

 event: {
    type: 'member_joined_channel',
    user: '***',
    channel: '***',
    channel_type: 'C',
    team: '***',
    inviter: '***',
    enterprise: '***',
    event_ts: '1736863796.000500'
  }

Is this intentional, or was it added at some point later by the web API, but the interface definition was not updated accordingly?

Packages:

Select all that apply:

• @slack/web-api
• @slack/rtm-api
• @slack/webhooks
• @slack/oauth
• @slack/socket-mode
• @slack/types
• I don't know

Reproducible in:

The Slack SDK version

"slack/bolt": "^4.2.0",
"slack-block-builder": "^2.8.0",

Node.js runtime version

v20.9.0

OS info

ProductName: macOS
ProductVersion: 15.2
BuildVersion: 24C101
Darwin Kernel Version 24.2.0: Fri Dec 6 19:01:59 PST 2024; root:xnu-11215.61.5~2/RELEASE_ARM64_T6000

Steps to reproduce:

1. Simply, setup an Event Listener with Bolt:

app.event('member_joined_channel', memberJoinedChannelCallback);

const memberJoinedChannelCallback = async ({
  client,
  event,
}: {
  client: WebClient;
  event: MemberJoinedChannelEvent;
}) => {
  console.log('Member Joined Channel event');
  console.log({ event });
});

Result:

 event: {
    type: 'member_joined_channel',
    user: '***',
    channel: '***',
    channel_type: 'C',
    team: '***',
    inviter: '***',
    enterprise: '***',
    event_ts: '1736863796.000500'
  }

Expected result:

Add the enterprise field to the interface, so it will correspond to the actual payloads that we receive.

Actual result:

Currently, the enterprise field is missing in the interface definition:
