Issue Summary

The Confluence REST API v2 endpoints getSpaces and getSpaceById return a homepageId: '0' value instead of a null value when the homepage does not exist.

Steps to Reproduce

1. Create a new space
2. Go to the homepage and delete it
3. Make the following requests:
   1. https://<domain-instance>/wiki/api/v2/spaces
   2. https://<domain-instance>/wiki/api/v2/spaces/<spaceId>
4. Both requests return the homepageId as '0' string value

{ id: 'xxx', key: 'TEST', name: 'TEST SPACE', type: 'global', status: 'current', authorId: 'xxx', createdAt: 'xxx', homepageId: '0', ... }

Expected Results

homepageId: null 

Actual Results

homepageId: '0' as string 

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
