Comments on an issue are not included in the Send Web Request payload, any idea why?

Issue

• I want to do a one way sync from 1 instance to another, using the Send Web Request automation action, and the Incoming Webhook on the target
• When there are comments on the source issue, these do not seem to be included in the payload at all
• Logging and inspecting {{webookData}} reveals no comment info
• If I fire the request off to pipedream or similar, I can't see any either
• 

Workaround

• I'm not savvy enough with Advanced edit to create the JSON structure for all of {{comments}}
• As a workaround, I write the following to a custom field

• {{#triggerIssue.comments}}
  *Comment by: {{author.displayName}} at: {{created.mediumDateTime}}*
  
  
  
  
  {{body}}
  
  ----
  {{/}}

• This is included in the payload received at the other end, and I can write a single comment to the newly created issue
• Then for new comments, I just have another pair of rules dealing with each comment, which works fine

Questions

• Does anyone know why the comments aren't included in the issue data for the Send Web Request action, where Issue Data is selected?
• Is there a better way to do this, without having to construct the entire JSON object myself as Advanced Field work?

Thanks everyone!
