I have a backend response, which is just a plain string (not wrapped in a JSON object, so like this: "12345"). Do I need to configure something special in the Kotlinx Serialization Json object for it to be parsed?

To be parsed from json, just decodeFromString<String>() , quoted string is valid json

Thank you, it also worked like this in tests.
