Hey @Florian, and welcome to our community 👋

Could you share your project name and the forest collection that implements the search on specific fields.

Can your confirm that your issue appears only in production not in local environment.

Hello @matthv and thank you !  
The project name is Ilek BO and the collection is Subscription.  
And yes, it only appears in production, it works in local environnement

Could your share the code of the Subscription collection too.

I’ll try to test on my end.

It doesn’t seem to be related to your implementation of search\_fields.

The log seems to indicate that there is an error on the apimap.  
Could you check that you have commit your .forestadmin-schema.json file along with your code?

I think, there is still a smart action in your schema and it no longer exists in your current code.

Yes it was commit when updating from 7.4.1 to 7.5.1 (even if it did not work with the previous version)

Here the meta settings :

```javascript
  "meta": {
    "liana": "forest-rails",
    "liana_version": "7.5.1",
    "stack": {
      "database_type": "postgresql",
      "orm_version": "6.0.4.7"
}

```

But now you mention it, i see an action on a collection :

```javascript
 "actions": [{
      "name": "Change password",
      "type": "bulk",
      "base_url": null,
      "endpoint": "forest/actions/change-password",
      "http_method": "POST",
      "redirect": null,
      "download": false,
      "fields": [{
        "field": "New password",
        "type": "String",
        "default_value": null,
        "enums": null,
        "is_required": false,
        "is_read_only": false,
        "reference": null,
        "description": null,
        "position": 0,
        "widget": null
      }],
      "hooks": {
        "load": false,
        "change": []
      }
    }]

```

Is it related ?

It might be related, this smart action is provided by our package if you use the devise gem.

However, have you recently used or removed the devise gem on your app?

Well, still not able to reproduce on my end.

I suggest you do the test to remove this smart action.  
Could you in your local environment comment out the line that defines `devise` on your `models/user.rb`

`#devise :database_authenticatable, :registerable, :recoverable, :rememberable, :validatable`

Then run your rails server, that will generate a new .forestschema-admin.json without the smart action.  
After that commit and push this schema to your production.

(don’t forget to remove the comment on the devise line)

We just successfully pushed in Production !!!  
Thanks for the help 💪  
The problem now is that dev will re-add the action when generating the forestschema.  
We can’t manage this manually each time.  
Do you know if a fix for this issue is going to be deployed in a future release ?
