kotlinx.serialization.SerializationException: Serializer for class 'UUID' is not found.

Mark the class as @Serializable or provide the serializer explicitly.

I know UUID is not serializable.
How do I do provide a serializer in Ktor?

[andylamax]

You should create a custom serializer for UUID

How exactly? Can you point me to some resource please?

But how do I annotate a class not defined in my source code, but in an external library?

[andylamax]

just follow the guide. You don't have to annotate the class by using your custom serializer
