Can anyone help on this what is the actual issue,how i can resolve this error.
I have faced the same issue. It was due to using Redistore with "express" parameter
var RedisStore = require('connect-redis')(express);
finally I fixed it using a session as parameter.
var session = require('express-session');
var RedisStore = require('connect-redis')(session);
Hope it helps you.

I'm trying to read CSV with Javascript, but I'm getting an error.
Here is my code:
fs.readFile('./data/AMZN.csv', async (err,data)=>{
if(err){
console.log(err)
return
}
console.log(data.replace("$",""));
})
Here is the example of my CSV data:
Date, Close/Last, Volume, Open, High, Low
09/11/2020, $3116.22, 5093982, $3208.69, $3217.3409, $3083.98
09/10/2020, $3175.11, 5330741, $3307.219, $3349.89, $3170.55
09/09/2020, $3268.61, 5188675, $3202.99, $3303.175, $3185
And here is the error that I get:
SyntaxError: Unexpected number

I've figured out that Javascript perceives $3116 as a string and the following .22 as a property of that string object, which can not be a number and therefore throws "Unexpected number".
But how do I fix it? I've been trying to deal with it for 2 days, but no luck so far.
The problem was in this line:
const AMZN = require("./data/AMZN.csv");
The code in the question works fine.
I have installed gulp-run-command as follows:
npm install gulp-run-command
I'm running a series of gulp tasks. All the others work, except this one. Here's the task where I'm running gulp-run-command:
var gulp = require('gulp');
var run = require('gulp-run-command');
gulp.task('testTask', run('testString'));
It is directly from the basic usage of gulp-run-command as shown here:
https://www.npmjs.com/package/gulp-run-command#usage
I get the following error as I run gulp:
TypeError: run is not a function

at requireDir (c:\mypath\node_modules\require-dir\index.js:76:33)
What's wrong here?
Ok, it worked as I added .default at the end of the line: var run = require('gulp-run-command');
So, like this:
var run = require('gulp-run-command').default
Error 471--cannot find module!
This is the model I am tring to write.T

listdate:DATATYPE.DATE,
available:DATATYPE.TEXT,

If you used Express framework, this example help you a lot:
https://github.com/sequelize/express-example/tree/master/models
I too had problems with Sequelize in the start.
Check especially:
models/index.js
models/user.js
routes/index.js
I have the below sample code which is failing if i pass ISODate in JSON object
var data =[{"$match":{"CREATED_DATE":{"$gt":ISODate("2015-07-29T17:30:00.000Z"),"$lt":ISODate("2015-07-30T09:00:00.000Z")}}}]
var update=JSON.parse(data);
Below is the error

I'm sure I'm doing something stupid, but I can't get node-fnoc to work. I have a directory with a simple package.json in it, I have a /config/ directory in that directory with a simple JSON file in it. And, I'm basically just trying to do what they have in their example.
var fnoc = require('fnoc');
fnoc(function(err, configs){
console.log(configs);
});
and this is what I'm getting:
fnoc(function(err, configs){

Any ideas?
The document on github is for version 0.2.2
You need to install fnoc#0.2.2
npm install fnoc#0.2.2
Run your js
node your.js
Output:
{ package:
{ name: 'asdf',
dependencies:
{ express: '*',
jade: '*',
Version is in the changelog file:
