Hello, This is my first time asking a question on a mailing list, so please forgive me any inaccuracies.
I am having a Kafka Streams application with a Punctuator. Inside the punctuate() I have this code: // fooStore is a state store for (FooKey fooKey : fooKeysRepository.get(Type.FOO)) { Foo foo = fooStore.get(fooKey); // foo != null This returns a Foo which is not null. FooKey has fields: [string(nullable), enum(nullable), string(nullable)] I extended enum with a new value, say BAZ (I appended that at the end of the enum) so it looks like: "symbols": [ "A", "B", ...., "UNKNOWN" "BAZ" ], "default": "UNKNOWN" and suddenly after this change, for (FooKey fooKey : fooKeysRepository.get(Type.FOO)) { Foo foo = fooStore.get(fooKey); // foo == null I'm at a loss to understand why this is happening. There is no exception, no trace in application logs, nothing. What's more, the FooKey is always represented as {"string", null, "string"} so the value for enum is consistently null. Cheers, Mariusz
