Content Delivery API circular reference - stack overflow

Vote:
 

Hi! We are using Content Delivery API for a model serialization. We are serializing the entire model and pass it to frontend. That means we have to expand all blocks/references. It was working fine till now. When we set expand="*" API expands only 2 levels deep. We can force API in code to expand all references unfortunately it ends with stack overflow exception because of the circular reference.

Example: Page has a block with a content area which might have a reference to our initial Page or parent of that Page and we get a circular dependency. 

Do you have any ideas how to solve this problem? It would be awesome to be able to set how deep the API should expand the properties. Filtering the references which causes the circular dependency might be also some solution. At least for now.

Any feedback from Optimizely here? Our website crashed because the frontend team added content to a ContentArea which had a reference to the other content, so a circular reference. How can we prevent that? This was the stacktrace before our site went down:

I think I saw this bug reported a while back. Let me dig for it

The bug was also about circular reference but in a different part/product.

Maybe we can do some detection here and throw more meaningful errors if you think that would be helpful? Otherwise circular reference detection can be very tricky at the time of editing

Thanks for the feedback. Is there a way to prevent this? So can we detect such a circular reference and validate it in the CMS? We had the issue for example when an ArticlePage was added to it's ContentArea property "Related Articles"(so references to another ArticlePage). Is the issue caused only if we add the same article as related article or even if it's a different page? But it could be that article1 is related to article2 which is related to article1, this must be allowed.

What would be the solution? Don't expand properties that cause this issue?

that's good question. Detect and prevent circular reference can be incredibly tricky. Out of my head, there could be scheduled jobs that does so (they could be too slow to run at saving/loading). for now, yes, the only workaround is to not expand the affected properties
