I have a field of type `Schema.Types.Mixed` on one of my models but it doesn’t seem to appear in the forest admin console for that model. I have tried going into the layout to add the field but it is not listed there either. How do I get it to appear in there? Thanks/

## Expected behavior

In the forest admin console, when I list my model instances, I should be able to see my field which is of type `Schema.Types.Mixed`, or at least be able to set it in the Layout Editor for that model.

## Actual behavior

It’s not available to add in the Layout Editor and is not visible when listing the instances.

## Failure Logs

N/A

## Context

Recently upgraded to v7 from v3 of `forest-express-mongoose`. I believe it was okay before this.

- Package Version: 7.7.1
- Express Version: 4.17
- Sequelize Version: n/a
- Database Dialect: MongoDB
- Database Version: 4.4.3

- did you add this field recently, to an existing project?

No, but I have upgraded from v7 of `forest-express-mongoose` since I last noticed it working.

- can you check if this field had been added to the file `forestadmin-schema.json` ?

Yes, but it appears to have a `null` value for the type

```javascript
}, {
      "field": "categoryScores",
      "type": null,
      "defaultValue": null,
      "enums": null,
      "integration": null,
      "isFilterable": true,
      "isPrimaryKey": false,
      "isReadOnly": false,
      "isRequired": true,
      "isSortable": true,
      "isVirtual": false,
      "reference": null,
      "inverseOf": null,
      "validations": [{
        "message": null,
        "type": "is present",
        "value": null
      }]
    }, {

```

- do you have any error in the console when starting your agent?

Sorry, not sure what you mean by the agent. Is that the process that uses `forest-express-mongoose`?

Hello @Richard_Garner,

Yes, by agent I mean the process that uses `forest-express-mongoose`. I’d like to know if there is any message in the console indicating that there is an error.

If you have access to the previous `forestadmin-schema.json` you had before the upgrade, could you please check if the field `categoryScores` is declared the same way?

What kind of values this field can contain?

Sorry for the delay. Before the upgrade the entry looked like this:

```javascript
}, {
      "field": "categoryScores",
      "type": null,
      "defaultValue": null,
      "enums": null,
      "integration": null,
      "isFilterable": true,
      "isReadOnly": false,
      "isRequired": true,
      "isSortable": true,
      "isVirtual": false,
      "reference": null,
      "inverseOf": null,
      "validations": [{
        "message": null,
        "type": "is present",
        "value": null
      }]
    }, {

```

The only difference I can see id that there is no `primaryKey` property before, although this is `false` anyway.

I have checked for errors in the logs too. There don’t seem to be any related to forest admin. All the forest endpoints called return successfully. On startup of my server, though, there is a Mongo warning, although this hasn’t caused any issues elsewhere and only happen on startup.

```javascript
(node:3911) Warning: Accessing non-existent property 'MongoError' of module exports inside circular dependency

```

The logs for the forest api calls look like this when I access the score items in the forest admin web console.

```javascript

Hello,

I tested with `forest-express-mongoose` v6 and v7, and I have the same behavior in both cases: the `Mixed` field is not displayed by Forest Admin.

What kind of data do you handle with this field?

Which version were you using before upgrading to v7?

It’s a simple shallow key pair object but the keys are dynamic.

And what version are you upgrading from?
