Client library/SDK language
None
Describe the bug
Discovered an issue when generating the Microsoft Graph V1.0 client library. The Kiota generated client library has added a breaking change that is not described by either a CSDL or OpenApi based change (unless missed, need to double check).
The issues are in microsoftgraph/msgraph-sdk-dotnet#3074. The issue is in Applications/Delta/GetDeltaResponse where the return type has been changed from Application to its base DirectoryObject.
Built Kiota, generated, and diff for these scenarios:
- v1.30.0
- main
- mmainer/fixDiscriminator (PR)
- pre v1.30.0 (todo)
Looking at the results of (v1.30.0 --> main) sdvdiff 6ccf6da832742181cba0ab02588c5795b2185e13 80bbd97a29fdac9f5c71694d712c85d946a9a117 may indicate that the cause is from the discriminator mapping.
Expected behavior
The generated client library uses the correct return type for the Appication getDeltaResponse
