Task Report does not load after Space import in Cloud

Summary

Task Report does not load after import in Cloud.
If a Space import is done with a Space using the Task Report macro on it, the link between report and tasks is lost because the ID of the page related in the task report macro changes, but the Task Report is not updated.

Steps to Reproduce

1. In another Confluence Server or Confluence Cloud create tasks on a page and a task report in another.
2. Export the Space with the Task Report.
3. Upload it and import it on Cloud.
4. Go to the task report macro page.

Expected Results

The tasks appear in the task report.

Actual Results

The tasks do not appear in the task report.

It might also display some null error message:

Notes

The task report macro references a different page ID:

• Wrong ID

  <p><ac:structured-macro ac:name="tasks-report-macro" ac:schema-version="1" ac:macro-id="d1d7b543-8e6c-468b-8977-638129fbf316"><ac:parameter ac:name="pages">12222498</ac:parameter></ac:structured-macro></p>
  

• Correct ID

  <p><ac:structured-macro ac:name="tasks-report-macro" ac:schema-version="1" ac:macro-id="444ec3a1-e72b-4280-bb49-e5bcea37e5c2"><ac:parameter ac:name="pages">8716290</ac:parameter></ac:structured-macro></p>
  

Workaround

Manually updating the report macro in edit mode usually fix the Macro so it renders the correct page.
