node.js - Handle partial success in async.parallel

Question

I am not able to find a way to handle error condition while I am making 2 services call using async.parallel. If one of the either call fails the entire call is failing, but I want to handle this failure and show the successful call in the response . Is there any way I can handle this ?

I have below code

var func1 = function(cb2) {
            svcCall1(jsonRequest, function(err2, res2) {
                if (err2) {
                    cb2(err2);
                } else {
                    cb2(null, res2)
                }
            })
    };

    var func2 = function(cb2) {
            svcCall2(jsonRequest, function(err2, res2) {
                if (err2) {
                    cb2(err2);
                } else {
                    cb2(null, res2)
                }
            })
    };

    async.parallel([func1, func2], function(err, data) {
// i want to handle here the partial success case.
        if (err) {
            callback(err);
        } else {`enter code here`
            callback(null, data);
        }

    });
