When you first create a project in Firebase, it will add a **rule** to the database to prevent access after 30 days. You can go to the `Rules tab` under `Realtime DB` and change the rule.

This is actually up to you.
You can keep the old rule but change the number to the date you want like next year.
You can just write `true` to make it accessible to anyone.
You can make `auth != null` which means users have to login
or `$uid === auth.uid` which means users can only change the data stored under their usernames.
You choose which security rule you want to apply.

How are you storing your data?
Is data stored under the user code retrieved from the `Sign In` component? If this is the case then you can use `$uid === auth.uid`
If you are nor sure then start with `auth != null`.
If you are **not** using the `Sign In` component then you have to use just `true`.

In this case, you need the `Rules` to look like this
```auto
{
"rules": {
".read": "true",
".write": "true"
}
}
```

The `rule` is correct. Just remove the last comma.
```auto
{
"rules": {
".read": "true",
".write": "true"
}
}
```

This could be due to many things, One thing to do is to use the `get block` and show the data retrieved in a label. Do the `get block` on something you know is available in the database and you can see it from the database console.
