Cannot type narrow APIApplicationCommandInteraction

Please describe the problem you are having in as much detail as possible:

When trying to type narrow interaction object, it is impossible to type narrow it to chat input. I looked at interaction types and I can’t work out why it is like that, so I’m asking for help. Maybe it is my issue, but I do not think so.

Include a reproducible code sample here, if possible:

I have function that takes interaction as APIChatInputApplicationCommandInteraction.

// Say you have an interaction and want to check if it's chat input (slash command)
if (interaction.type === 2 && interaction.data.type === 1) {
  // here interaction should definitely be chat input
  // but it's not, it still APIApplicationCommandInteraction
  // and can't assign to APIChatInputApplicationCommandInteraction
  await this.execute(interaction); // Type "APIApplicationCommandInteraction" not assignable to "APIChatInputApplicationCommandInteraction"

Further details:

• Runtime:
  • Node.js version: v17.5.0
• Priority this issue should have – please be realistic and elaborate if possible: Medium because it is a bug but can be bypass, e.g. by interaction as APIChatInputApplicationCommandInteraction

Also interaction type guards just got merged in to 0.28.0 in utils, so I guess this is solved 😃
