Additionally I’m having issues with the quick start authenticating

in the UI:

```auto
Object.fromEntries is not a function

```

In the console:

```auto
Uncaught (in promise) TypeError: Cannot read property 'sessionId' of null
    at Object.authenticate [as click] (flow-
authenticate.js:44)

```

which maps to:

> <https://github.com/onflow/flow-js-sdk/blob/master/packages/dev-wallet/src/pages/flow-authenticate.js#L44>

  
And the error coming back from dev-wallet GraphQL server is

```auto
{
   "errors":[
      {
         "message":"Object.fromEntries is not a function",
         "locations":[
            {
               "line":3,
               "column":5
            }
         ],
         "path":[
            "authenticate"
         ]
      }
   ],
   "data":{
      "authenticate":null
   }
}

```

Are you use any login/password? 🤔

The quick start labels the button as “Sign in / up” which I interpreted as meaning the auth / wallet form is for both creating an account (if it’s not a recognized email) or logging in (if it is).

If that’s not the case and indeed there is a pre set email/password to use with the FCL dev wallet I did not find it in any of the docs.

@lukehamilton this looks like a node version issue at first glance? What version of node are you using with the dev-wallet?

In your console you should be able to run something like this:

```auto
$ node -v
v13.7.0

```

</div>

I’m using the following.

```auto
❯ quickstart (master) ✘ node -v
v10.16.3

```

Is there a node version requirement?

When I switch to node 12 it works

```auto
v12.10.0

```

What version of node are you all using for development? So I can use the same one with these libraries.

I am also following the readme of [https://github.com/onflow/flow-js-sdk/tree/master/packages/fcl](https://github.com/onflow/flow-js-sdk/tree/master/packages/fcl) but wasn’t sure how to set username/password so I can run script but cannot run any transactions.
