Missing Typescript Types for Slack Interactive Messages

[jaalger]

Botkit Version: 0.6.13

Building Typescript Slack Bot using Botkit and ran into issues regarding type checking:

SlackAttachment interface missing the following:

• actions
• attachment_type
• callback_id

Message interface missing the following:

• replace_original
• response_type

Type check errors all follow a similar error message:

Object literal may only specify known properties, and 'callback_id' does not exist in type 'SlackAttachment'.

Was able to workaround the issue with either of the two workarounds below:

1. Added missing types locally to https://github.com/howdyai/botkit/blob/master/lib/Botkit.d.ts
2. Changed the ts file to a js file and updated my compiler to allowJs.
