Answer 1

Check if you have quotes. Escape them with \"Sometext\". Example YAML:

---
title: Bad relationships still require work. Don't compromise
lastUpdate: 19 July 2021
tags: ['personal', 'relationships', 'compromise']
slug: bad-relationships-require-work
meta:
  title: Bad relationships still require work. Don't compromise
  description: "ERROR HERE The relationship is bad, therefore I can maintain it with less work. ERROR HERE" That's usually a sneaky fallacy.
---

See ERROR HERE. Quotes should have been escaped

Under sources:, the URL should be on the same line as - url:, and I think you need to specify the branches to use.

As defined, your URLs are relative, but look like maybe they should be absolute. Provided that those paths resolve correctly from the folder where you invoke Antora, they should work fine.

The bundle: URL must point to a ZIP file of a bundled Antora UI. You cannot simply use a folder that represents a UI. In my example below, I've replaced the URL you were using with the URL for Antora's default UI.

So your playbook file should look more like:

site:
  title: Antora Demo Site
  url: https://example.org/docs 
  start_page: antora-project::index-template.adoc 
content:
  sources:
  - url: home/Users/rashmi.p1/Sample/antora-project/content/feature1
    branches: HEAD
    start_path: docs
  - url: home/Users/rashmi.p1/Sample/antora-project/content/feature2
    branches: HEAD
    start_path: docs  
ui:
  bundle:
    url: https://gitlab.com/antora/antora-ui-default/-/jobs/artifacts/master/raw/build/ui-bundle.zip?job=bundle-stable
    snapshot: true

I have faced same exception, but not for same issue. My issue was under description:, which is under parameters:. There I kept some space only by mistake. After removing the space, it worked.

Hope it helps.
