System.InvalidOperationException: Failed to Fetch Ancestors - Internal Server Error (500) Due to Content Cache Retrieval Failure in Umbraco Delivery API
#17165
Which Umbraco version are you using? (Please write the exact version, example: 10.1.0)
13.5.1
Bug summary
When making a GET request to the Umbraco Delivery API (v2) to fetch ancestor content using the fetch=ancestors parameter for a specific content ID that is unpublished, the server returns a 500 Internal Server Error. The error is triggered by a System.InvalidOperationException, indicating that the content cache could not be obtained due to the unpublished state of the target content. This issue arises during the execution of the ApiContentQueryService while processing the query with the AncestorsSelector.
Additional Notes:
The content ID being queried is unpublished, which may contribute to the failure of obtaining the content cache.
Stack Trace Highlights:
System.InvalidOperationException: Could not obtain the content cache

Screenshots of where the issue is happening in code
The previewdefault is not set to true even through we have sent the corrent query params (api-key and preview)
This could be caused by the following code not detecting the preview mode correctly and are currently only looking at the cookies and not query params for preview state. However not completely sure😊
Steps to reproduce
Steps to Reproduce:
Attempt a GET request to the endpoint /umbraco/delivery/api/v2/content with the fetch=ancestors parameter.
Ensure the request targets an unpublished content ID and includes valid authentication headers (API key, preview mode).
Observe the 500 Internal Server Error returned by the server.
Actual Behavior: The API returns a 500 Internal Server Error due to a failure in retrieving the content cache, particularly for the unpublished content.
Expected Behavior: The API should successfully return the available ancestor data when preview mode is set to true and has correct preview api key

Firstly, a big thank you for raising this issue. Every piece of feedback we receive helps us to make Umbraco better.
We really appreciate your patience while we wait for our team to have a look at this but we wanted to let you know that we see this and share with you the plan for what comes next.
We'll assess whether this issue relates to something that has already been fixed in a later version of the release that it has been raised for.
If it's a bug, is it related to a release that we are actively supporting or is it related to a release that's in the end-of-life or security-only phase?
We'll replicate the issue to ensure that the problem is as described.
We'll decide whether the behavior is an issue or if the behavior is intended.
We wish we could work with everyone directly and assess your issue immediately but we're in the fortunate position of having lots of contributions to work with and only a few humans who are able to do it. We are making progress though and in the meantime, we will keep you in the loop and let you know when we have any questions.
We also suffer from this problem, can confirm the workaround works. Adding this because I had to look it up, you can add the middleware in your Composer like so:
