The error occurs in the following Apple library: https://github.com/apple/app-store-server-library-java/blob/main/src/main/java/com/apple/itunes/storekit/verification/SignedDataVerifier.java#L172

To find out the cause of this, please let me know the correct code to use when returning an HTTP status code in Java. Also, could the library version of the App Store Server API be related as another cause? Or are the settings in App Store Connect related?
