## Expected behavior

No error

## Actual behavior

We get a `TypeError: ResourceGetter is not a constructor` when using `ResourceGetter`:

```javascript
const { ResourceGetter } = require('forest-express-sequelize')

const resourceGetter = new ResourceGetter(models.orders, { recordId: orderId })
const order = await resourceGetter.perform()

```

However I see in the codebase that our syntax looks correct: [forest-express-sequelize/databases.test.js at 7cceb40153165b65089df011ed4acd02fbcdb97a · ForestAdmin/forest-express-sequelize · GitHub](https://github.com/ForestAdmin/forest-express-sequelize/blob/7cceb40153165b65089df011ed4acd02fbcdb97a/test/databases.test.js#L2167)

## Failure Logs

Nothing more than the TypeError

## Context

Please provide any relevant information about your setup.

- forest-express-sequelize: 6.6.3
- forest-express: 7.9.4
- Express Version: 4.17.1
- Sequelize Version: 5.19.6
- Database Dialect: Postgres
- Database Version: -
- Project Name: UrbanCampus - Platform
- Environment: all of them

It’s pretty urgent for us as we noticed the issue on prod and just upgraded from v5 to v6 so we’d like to avoid a rollback… Thanks

Hi @cberez,

Could you check that you required the `ResourceGetter` properly at the beginning of the file on which the error is happening?

```javascript
{ ResourceGetter } = require('forest-express-sequelize');

```

Hi @anon37102731,

Here’s the require line (updating the original message too):

```javascript
const { ResourceGetter } = require('forest-express-sequelize')

```

</div>

To be more precise: it’s an old code that’s been there for some time and used to work, now we get the `TypeError`, it seems since we upgraded to 6.6.3

@cberez I just looked at the code and the `ResourceGetter` service is not exposed through `forest-express-sequelize`. It’s only intended to be used internally.

However, a `RecordGetter` is exposed to perform the kind of record retrieval logic you’re trying to build. You can find several example of this `RecordGetter` usage on our [documentation](https://docs.forestadmin.com/documentation/reference-guide/routes/default-routes#get-a-record).

I hope you’ll find what you need in there!

Ah must’ve been hidden on latest versions, our code dates back to v4

Thanks I’ll have a look to the `RecordGetter`
