Getting error when accessing any of the methods through explorer ("Cannot call ACL.find(). The find method has not been setup. The PersistedModel has not been correctly attached to a DataSource!)

Just testing out of the box.

When trying any of the methods through localhost:3000/explorer I'm getting:

    {
      "error": {
        "name": "Error",
        "status": 500,
        "message": "Cannot call ACL.find(). The find method has not been setup. The PersistedModel has not been correctly attached to a DataSource!",
        "stack": "Error: Cannot call ACL.find(). The find method has not been setup.

      }
    }

I was expecting to get 401 instead.

I tried to check what the problem could be, but User etc are connected to datasource db which is correctly configured afaik. (I changed nothing at model-config.json and datasources.json)

btw: client-secrets, etc. are configured correctly and the webapp appears to function correctly as well.

Anyone knows that's up?

loopback : 2.1.4 loopback-example-passport: 2.0.0

I went a bit too far. Some of the built-in models such as ACL lost the DB config. It should be fixed now in master.

yup, that solve it. Thanks!

I am getting this error. Using Loopback 3

Error: Cannot call ACL.find(). The find method has not been setup. The PersistedModel has not been correctly attached to a DataSource!

I am getting this error for programmatically defined models but not for models created using the generator.

Hi, please check your model-config.json file. I realised I had mistakenly removed the ACL part of it so please make sure that it is there like so...

  "ACL": {
    "dataSource": "db",
    "public": false
  },
