I don't know what you are using to post those logs, but having no line feeds in them make them very hard to read.
Means you are sending the response to a channel called 'toPersist' and there is nothing currently subscribed to it (has it as an input-channel).
Dispatcher has no subscribers for channel toPersist.
Since that channel is not in the configuration in your first post, I can't tell exactly what you are trying to do with the response.
