Sync code for Promise All

Hi everyone I'm having troubles with my code because of promises are being done in a async way and i need them to be sync. So I have this function to return the value of the two promises inside fullfilled

ServicesController.prototype.uci = function (device, config, path, section, property, value, apply, commit) {
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'inicio');

    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'config', config);
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'path', path);
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'section', section);
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'option', property);
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'value', value);
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'apply', apply);
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'commit', commit);

    var values = {};
    values[property] = value;
    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'values', values);

    return Controllers.Ubus.uciRequest('set', {"config": config, "section": section, values}, device)
            .then(function (uciData) {
                createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'uciData', uciData);
                var promises = [];

                if (uciData != null) {
                    createLog('info', __dirname, __filename.slice(__dirname.length + 1, -3), device.id, 'uci', 'depois do if do uciData');

                    if (commit) {
                        createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'commit');
                        var p1 = Controllers.Ubus.uciRequest('commit', {"config": config}, device)
                                .then(function (dataCommit) {
                                    if (dataCommit && dataCommit.hasOwnProperty('result') && dataCommit.result[0] == 0) {
                                        createLog('info', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'commit data', dataCommit);
                                    }
                                })
                        promises.push(p1);
                    }

                    if (apply) {
                        createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'apply');
                        var p2 = Controllers.Ubus.fileExec(device.id, "exec", path, "restart")
                                .then(function (dataApply) {
                                    if (dataApply && dataApply.hasOwnProperty('result') && dataApply.result[0] == 0) {
                                        createLog('info', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'apply data', dataApply);
                                    }
                                })
                        promises.push(p2);
                    }
                }
            }).then(function (promises) {
                createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'promises then', promises);
                return Promise.all(promises).then(function (values) {
                    createLog('debug', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'promises all', values);
                }).catch(function (err) {
                    createLog('error', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'error promise all', err);
                });
            }).catch(function (err) {
                createLog('error', __dirname, __filename.slice(__dirname.length + 1, -3), null, 'uci', 'error then 2', err);
            });
}

By my logs I'm entering in the apply and commit if.

Right now i'm receiving this log:

 [2017-06-08 15:37:39.621] - error: /opt/wscontroller/wscontroller-api/routes/services ServicesController NA uci error promise all {}

Anyone can give me some help to solve this problem?
