When clicking on the release note link for any update where the App is set to Studio, the link does not work as expected.

Steps to Reproduce:
1. Navigate to admin.atlassian.com
2. Go to Release Management → App Updates
3. Find any update where the App is Studio
4. Click on the release note link

Expected Behaviour:
The release note link should open the relevant release notes page for the Studio update.

Actual Behaviour:
Clicking the link results in a "We're not sure what went wrong" error page being displayed.

Root Cause (from Network Tab):
The products endpoint returns a 500 Internal Server Error with the following response:

{
    "id": "7563b716f51642729a5bb30fac68c565",
    "status": 500,
    "title": "Internal Server Error",
    "detail": "JSON decoding error: Instantiation of [simple type, class io.atlassian.micros.releasemanagement.productupdates.model.adminportfolio.Attributes] value failed for JSON property hostUrl due to missing (therefore NULL) value for creator parameter hostUrl which is a non-nullable type",
    "timestamp": "2026-07-29T04:53:30.324645833Z",
    "error": "JSON decoding error: Instantiation of [simple type, class io.atlassian.micros.releasemanagement.productupdates.model.adminportfolio.Attributes] value failed for JSON property hostUrl due to missing (therefore NULL) value for creator parameter hostUrl which is a non-nullable type",
    "message": "Internal Server Error"
}

The error suggests that the hostUrl property is null for Studio app entries, but the Attributes model requires it to be non-nullable.

Additional Notes:

• This issue is specific to Studio app updates — release note links for all other apps work correctly.
