How to resolve the error when next() step is used in gremlin?

Previously I have used janusgraph-0.2.0-hadoop2 server and gremlin@2.6.0 library for querying.My queries worked fine. But, now I have updated to latest versions(janusgraph: latest, Cassandra: 3, elastic search: 6.6.0) and janusgraph-0.5.0-hadoop2 server. For janusgraph-0.5.0-hadoop2 server and gremlin@2.6.0 library, the following query

g.addV('Location') .property('locationId', 'afdvbd-w6POkbQTq') .property('active', false) .as('place') .V().hasLabel('user').has('userId', 'hhdfjgygkgkdgfyukdgd') .as('person') .addE('createdBy').from('place') .property('on', 1589278312249).next()

results an error

Exception while adding place to graph Error: java.util.NoSuchElementException (Error 597) at GremlinClient.handleProtocolMessage (/srv/node_modules/gremlin/lib/GremlinClient.js:182:37) at WebSocketGremlinConnection.connection.on.message (/srv/node_modules/gremlin/lib/GremlinClient.js:108:46) at emitOne (events.js:116:13) at WebSocketGremlinConnection.emit (events.js:211:7) at WebSocketGremlinConnection.handleMessage (/srv/node_modules/gremlin/lib/WebSocketGremlinConnection.js:45:10) at WebSocketGremlinConnection.ws.onmessage.message (/srv/node_modules/gremlin/lib/WebSocketGremlinConnection.js:30:41) at WebSocket.onMessage (/srv/node_modules/ws/lib/EventTarget.js:103:16) at emitTwo (events.js:126:13) at WebSocket.emit (events.js:214:7) at Receiver._receiver.onmessage (/srv/node_modules/ws/lib/WebSocket.js:146:54)

The same query when I am running by updating the gremlin library to 3.4.6, then the result is as follows

And my javascript snippet is

/**
 * @param {Object} options
 * @param {} options.userId 
 * @param options.client // this is the gremlin client to run queries onto graph database.
 * @throws {Error}
 * @return {Promise}
 */
module.exports.addLocation = (options) => {
  const location = options.location;
  const admin = options.admin;
  const createdOn = new Date().valueOf(); // TODO: timestamp entered into Firestore. Same value should be given here

  console.log('addLocation invoked', location);
  console.log('Options obtained', options);
  return new Promise((resolve, reject) => {
    if (options.userId !== options.reqUserId) {
      console.log(`UserId: ${options.userId}, reqUserId: ${options.reqUserId}`, options);
      return reject({
        status: 401,
        body: 'Unauthorized. You can\'t impersonate other users!'
      });
    }
    console.log('validating the location');
    const errors = validate(location, 'Model');
    if (errors) {
      console.log('Error while validating the locations:', errors);
      return reject({
        status: 405,
        body: errors
      });
    }
    const locationId = `${location.name.replace(/\s+/g, '-').replace(/[^a-zA-Z0-9-_]/g, '').toLowerCase()  }-${  shortid.generate()}`; //TODO: id obtained from firestore
    console.log(`Created dynamic location id: ${  locationId}`);

    location['locationId'] = locationId;
    location['createdDate'] = new Date();
    location['lastUpdatedDate'] = new Date();
    if (location.publishedDate) story['publishedDate'] = new Date(location.publishedDate);
    if (location.unpublishedDate) story['unpublishedDate'] = new Date(location.unpublishedDate);
    console.log(`updated location: ${ JSON.stringify(location)}`);
    //TODO: get the ID of the story and use it to make entry into Graph
    const name = location.name;
    const active = false;
    const inputParams = {
      userId:options.userId,
      locationId,
      name,
      active,
      createdOn
    };
    console.log('adding location to graph');
    const query = `g.addV('Location') .property('locationId', locationId) .property('active', false) .as('place') .V().hasLabel('user').has('userId',userId ) .as('person') .addE('createdBy').from('place') .property('on', 1589278312249).next()`;
    console.log(`query: ${query}  inputParams:`, inputParams);
    options.client.executeGraph(query, inputParams).then(res => {
      if (res.length > 0) {
        console.log('Successfully added the location to graph');
        console.log('adding location to firestore');
        
        
        const createdlocation = location; // TODO: replace with actual object.
        admin.firestore().doc(`cms/ugc/locations/${  locationId}`).set(location).then(() => {
          console.log('succesfully added location to firestore ');

          return resolve({
            status: 200,
            data: createdlocation
          });
        }).catch((err) => {
          console.log('Error while adding location to firestore:', err);
          return reject({status:500, error: err});
        });
      } 
    }).catch(err => {
      console.log('Exception while adding location to graph', err);
      return reject({
        status: 500,
        error: err
      });
    });
  });
};

But, while running the same query in gremlin console with static data and also by removing the next() step, then it is working perfectly fine.

Don't know the exact issue, but I thought of next() step in latest versions maynot work correctly.It is a wild guess but I am not getting how to resolve it. Any help would be greatly appreciated. Thanks in advance!
