node mssql stream return issue - sql-server

Question

I am attempting to stream the data from a procedure that returns multiple data sets using node and mssql. If using as a stand a long function it works, but I need it to return the dataset from the route i am using.
handler: function(request, reply) {
var inputValues = request.payload.inputParams;
var procName = request.params.procedureName;
var request = new sql.Request(mainsettings.connection);
request.stream = true;
var newGroup = [];
var count = 0;
var recordSetArr = [];
for(var key in inputValues) {
var currentParam = inputValues[key];
var paramType = getParamType(sql, currentParam.paramType);
try {
request.input(currentParam.paramName, paramType, currentParam.paramValue);
}
catch(err) {
console.error(err);
}
}
request.execute(procName);
request.on('recordset', function(columns) {
// Emitted once for each recordset in a query
count++;
if(count > 1) {
recordSetArr.push(newGroup);
}
newGroup = [];
});
request.on('row', function(row) {
// Emitted for each row in a recordset
newGroup.push(row);
});
request.on('error', function(err) {
// May be emitted multiple times
console.error(err);
});
request.on('done', function(returnValue) {
// Always emitted as the last one
return (recordSetArr);
});
}
I am getting the following error.
Debug: internal, implementation, error
Error: handler method did not return a value, a promise, or throw an error

Any suggestions on how I am supposed to return the data set properly?
Also tried the following
handler: function(request, reply) {
recordRouteCall("procedure");
var inputValues = request.payload.inputParams;
var procName = request.params.procedureName;
sql.connect(mainsettings.connection, err => {
var request = new sql.Request();
request.stream = true;
var newGroup = [];
var count = 0;
var recordSetArr = [];
for(var key in inputValues) {
var currentParam = inputValues[key];
var paramType = getParamType(sql, currentParam.paramType);
try {
request.input(currentParam.paramName, paramType, currentParam.paramValue);
}
catch(err) {
console.error(err);
}
}
request.execute(procName);
request.on('recordset', columns => {
// Emitted once for each recordset in a query
count++;
if(count > 1) {
recordSetArr.push(newGroup);
}
newGroup = [];
});
request.on('row', row => {
// Emitted for each row in a recordset
newGroup.push(row);
});
request.on('error', err => {
// May be emitted multiple times
console.error(err);
});
request.on('done', result => {
// Always emitted as the last one
console.log(recordSetArr);
return (recordSetArr);
});
});
sql.on('error', err => {
console.error(err);
return err;
});
}
