Node.JS Restify and post Events - node.js

Question

Hello I have a post event that takes in key value and maps it to a sproc. This part works very well. However, for some reason I cannot return the data response as JSON.
It says the return type is "octet stream" even though I'm setting it to application/json.
I'm a little new to REST, so if I'm doing something incorrectly, please let me know.
server.post({ path: PATH + '/data.json', version: '1.0' }, genericData);
function genericData(req, res, next) {
if (req.params.data != null){
var sp_code_name = config.get('data:' + req.params.data);
var connection = new sql.Connection(conn_str, function(err) {
// ... error checks
if(err) {
return console.log("Could not connect to sql: ", err);
connection.close();
}
});
var request = new sql.Request(connection);
console.log(sp_code_name);
request.execute(sp_code_name, function (err, recordset, returnValue) {
if (err) {
connection.close();
return console.log("Is this a good query or the right table?: ", err);
}
//if (recordset && returnValue == 0) {
res.setHeader('Access-Control-Allow-Origin','*');
res.setHeader('content-type', 'application/json');
res.send(200, recordset[0]);
console.log(recordset[0]);
// return next();
// }
// return next();
connection.close();
});
}
res.setHeader('content-type', 'application/text');
res.send(200, "Something is wrong with the stream.");
}

You need to wrap your error response in an else clause:
if (req.params.data != null){
...
} else {
res.setHeader('content-type', 'application/text');
res.send(200, "Something is wrong with the stream.");
}
Without the else clause, it's getting called on every request before your request.execute callback is called. That's setting your content-type to application/text instead of application/json as you're expecting.
