Steps to reproduce

Create a model with property type array:
e.g:

"propertyKey": {
      "type": [
        "string"
      ]
    }

Insert some records.
Try to filter the record: {where: { propertyKey: "somevalue"}}

Current Behavior

It doesn't return any records for the filter.
However, using loopback-connector-mongodb@5.2.3 package returns the desired response.

Expected Behavior

It should return matching records.
