If you're making any calls to res.render
such as in an error handler that are generated by the 'express generate', then you'll see the error you described. For a json API service you probably don't need to render anything so just don't call render()
, instead call res.send()
with the status res.status set to 404 or 500.
So basically, replace this:
app.use(function(err, req, res, next) {
res.render('error', {
message: err.message,
error: err
});
});
with this:
app.use(function(err, req, res, next){
res.status(err.status || 500);
res.send({
message: err.message,
error: err
});
return;
});
