Generator creates an empty channel by default - breaks the rendering

[IsmaelMartinez]

I tried this:

I used the generator to create events that link to a service.

This generates by default an empty channel. I believe then eventcatalog assumes there is no channel associated, so it doesn't link them together.

This happened:

Example of the frontmatter generated

---
id: id
name: name
version: '1'
schemaPath: name-openapi.json
badges:
  - content: 'Source: name'
    backgroundColor: pink
    textColor: pink
  - content: 'DetailType: undefined'
    backgroundColor: pink
    textColor: pink
  - content: 'Schema name: name'
    backgroundColor: pink
    textColor: pink
channels: [] <----
---
## Overview

This then fails to render the "lines" in the graph.

I expected this:

Expected to render correctly in the UI, and/or to have a 'eventbridge' channel.

Is there a workaround?

You can remove the "channels: []" section in each event and then it renders fine.

Anything else?

I believe this line

generator-eventbridge/src/index.ts

Line 300 in 6c78684

let eventChannel = [] as any;

is the culpit as we should only add channels if there are any. Otherwise the rendered thinks there is a channel of communication (that is empty).

I will see if I can do a PR later today to fix that area and allow for setting that as null if there aren't any channels.

I have created a PR with the fix for this and the detailType (that was showing as undefined).

Both are conditional and should not break previous implementations. This is probably related to us using a custom schema registry instead of the autodiscovery one.
