Updating the home page of a newly created space does not work

Issue Summary

After creating a brand new space, if the user tries to update the overview page, the following message will be displayed:

"This content cannot be accessed.

Your session may have expired. You'll need to log in again or switch to another account to keep working."

Steps to Reproduce

1. As a user with permission to create spaces, create a new Confluence space.
2. Edit the home page of the space, but do not add new content nor remove content from it.
3. Try to publish the page.

Expected Results

The page should be published.

Actual Results

The following message is displayed, blocking the page to be published:

In the browser console, we can see a 404:

{"statusCode":404,"data":{"authorized":false,"valid":true,"errors":[],"successful":false},"message":"com.atlassian.confluence.api.service.exceptions.NotFoundException: null"}

Workaround

Different workarounds can be used for this one. Note that for each, waiting a few seconds to get the changes synced should ensure that this will work:

• Remove parts of the content of the home page and add the new content.
• If the content is not supposed to be used, simply delete it all and add the new changes prior to publishing the page again.
• Add new content to the home page.
• Change the title of the home page.
