res.serverError()
This method is used to send a 500 ("Server Error") response back down to the client, indicating that some kind of server error occurred (i.e. the error is not the requesting user agent's fault).
Usage
return res.serverError(err);
Or:
return res.serverError();
Details
Like the other built-in custom response modules, the behavior of this method is customizable.
By default, it works as follows:
The status code of the response will be set to 500.
If the request "wants JSON" (e.g. the request originated from AJAX, WebSockets, or a REST client like cURL), Sails will send the provided error
dataas JSON. If nodatais provided, a default response body will be sent (the string"Internal Server Error").If the request does not "want JSON" (e.g. a URL typed into a web browser), Sails will attempt to serve the view located at
views/500.ejs(assuming the default EJS view engine). If no such view is found, or an error occurs attempting to serve it, a default response body will be sent with the string"Internal Server Error".
Example
return res.serverError('Salesforce could not be reached');
Notes
- This method is terminal, meaning that it is generally the last line of code your app should run for a given request (hence the advisory usage of
returnthroughout these docs).
res.serverError()(like other userland response methods) can be overridden or modified. It runs the response method defined inapi/responses/serverError.js. If aserverError.jsresponse method does not exist in your app, Sails will use the default behavior.
- The specified
datawill be excluded from the JSON response and view locals if the app is running in the "production" environment (i.e.process.env.NODE_ENV === 'production').
