Subject: [PATCH] added res.sendStatus(200); to stop client errors throwing

according to the docs
"The methods on the response object (res) in the following table can send a response to the client, and terminate the request-response cycle. If none of these methods are called from a route handler, the client request will be left hanging."
Last sentence is the critical one.
Sending a status code 200 should fix the issue
