validator has not been provided for attribute ... of type 'object'

[bradjones1]

I am working with v0.17.0-beta.20 utilizing a json:api source pulled through an in-memory source. While syncing the record cache, the record is validated. I have a model for a file record type, with an attribute of object type specified thusly:

{
  "models": {
    "file": {
      "attributes": {
...
        "uri": {
          "type": "object"
        },
...
        }
      }
    }
  }
}

In SyncRecordCache::update, the validation fails with the following issue:

It appears this is related to #842 but as there is no documentation yet on 0.17 beyond the tests, I'm a bit stumped as to whether this is a:

• bad model definition (there are no examples of object attributes in the current docs or tests)
• regression/bug with the new validator model
• something else?

Looks like we're missing an object validator:

orbit/packages/@orbit/validators/src/standard-validators.ts

Lines 8 to 29 in e4a9395

	export enum StandardValidators {
	Array = 'array',
	Boolean = 'boolean',
	Date = 'date',
	Number = 'number',
	String = 'string'
	}
	export type StandardValidator =
	| ArrayValidator
	| BooleanValidator
	| DateValidator
	| NumberValidator
	| StringValidator;
	export const standardValidators: Dict<StandardValidator> = {
	array: validateArray,
	boolean: validateBoolean,
	date: validateDate,
	number: validateNumber,
	string: validateString
	};

Good catch, @bradjones1.

In reviewing the validator logic, I found a few holes that I'm going to try to fill today:

• the missing object validator (which will probably just do a typeof check)
• datetime fields should be validated with the same date validator
• the concept of an unknown validator to allow for a catch-all for validating types that don't have a registered validator (similar to the unknown serializer concept)

I'll get a new beta out after this work is done.

In the mean time, if you want a workaround to avoid the above error you can provide a custom validatorFor function to your sources that includes a no-op validator (() => {}) for object.
