Newtonsoft.Json: Self referencing loop detected for property 'Parent' with type 'Microsoft.Azure.Cosmos.Tracing.Trace'.

We are continuously addressing and improving the SDK, if possible, make sure the problem persist in the latest SDK version.

Describe the bug Using continuationToken does not work

To Reproduce

1. Create an Azure Function HTTP Trigger
2. Inside the Azure Function, query for a paginated collection
3. Invoke the Azure Function without passing the continuationToken
4. Return the paginated result together with the FeedResponse<T>.ContinuationToken
5. Invoke the Azure Function again and pass the continuationToken

Expected behavior This should get the next page

Actual behavior Getting the following error

System.Private.CoreLib: Exception while executing function: Some_Paginated_Function. Newtonsoft.Json: Self referencing loop detected for property ‘Parent’ with type ‘Microsoft.Azure.Cosmos.Tracing.Trace’. Path ‘Item3.Diagnostics.Value.Children[0]’.

Environment summary SDK Version: Microsoft.Azure.Cosmos v3.22.1 OS Version: MacOSX 12.0.1

Additional context Nothing else is thrown in the terminal

Can we close this Issue then?

What I did is return it as a deserialized object from the endpoint and let the client (mobile app) handle it and encode/serialize it back to a json string. And by the time it is needed to be used in the query parameter of the HTTP request, I make sure that it is URL Encoded.

I implemented this after you replied with the reference link.

This approach worked on my end and I got the same format back.
