How to deal when calling a wrong endpoint using app.get?

I have several endpoints defined. I am doing the automation of all of them and in addition defining some scenarios where I should get an error.

For instance, one of the endpoints is: '/v1/templates'.

Now, imagine that by error, the user types '/v1/templatess'.

I am using app.get to deal with the known endpoints like this:

app.get(
    '/v1/contents/:template_component_content_id',
    controllers.template_component_contents.getById.bind(controllers.template_component_contents)
);

Is there any way to say that in case that the endpoint called does not match with any of the app.get() options, throw an ERROR?

Thanks in advance.
