secret URL sharing shows error when accessed as loggedout user

[Cecilia Vela Gurovic]

Steps to replicate:

- Create a page
- Click on Share and create a new secret URL
- Copy the link and logout
- Access the URL
- Refresh the page
Expected result: The empty page is displayed
Actual result:
We see error

When I share the page via secret URL, I get the following error message:
