Question: I am following [this tutorial (using meteor on modulus)](http://help.modulus.io/customer/portal/articles/1647770-using-meteor-with-modulus) to test telescope app and how the deploy works

I am getting this error :

Thank you !!

Answer: 
This is a common issue when you don't redeploy the application after the first step.

run this 2 commands.

```
modulus project restart
modulus deploy

```

**NOTE** be sure the URL don't have any blank space either.
From step three of the tutorial,
