What type of error object is retuned from a http call if statusCode is not 200?

I am making http calls in meteor using the npm 'request' package.

I would like to know what type of error object is created when a response.statusCode is not equal to 200? Is this handled by the javascript engine and considered a runtime error?

Or if the statusCode is not equal to 200 is determined by the service provider whether they will create an error object or not?

If the latter, do I create a 'manual error', new Error('throwing my own error for the catch block to handle')

var request = function() {
// HTTP call to server
  },  
  function (error, response, body) {    
  if (!error && response.statusCode === 200) {
    // processed and created data object
      return data
  }
  else {
     return (error) ; // How can I ensure the catch(e) block in the try/catch method will catch the error with an addition of my own 'message'. 
  }
})
};

try {
    request()
}
catch(e) {
  console.log(e)
}

For my scenario, I would like to ensure the catch(e) block will grab this error and I would like to add my own message including the stack trace.
