invokeAction return type incorrect?

[jacobweber]

If I call rest.invokeAction<ResponseType>, the TypeScript definitions and documentation say that it returns something like:

[
  {
    actionName: '',
    isSuccess: true,
    errors: [],
    outputValues: {
      output: ResponseType
    }
  }
]

I think this is incorrect — outputValues should actually be an object of type ResponseType, and shouldn't contain an "output" field. If I log the response, that's what it contains, and it's consistent with the example in the actions developer guide.

that does seem to be the case. PR welcomed, otherwise I'll try to get around to it when I can!

@jacobweber I just tested this with a custom apex invocable:

public class AccountInsertAction {
  @InvocableMethod(label='Insert Accounts' description='Inserts the accounts specified and returns the IDs of the new accounts.')
  public static List<ID> insertAccounts(List<Account> accounts) {
    Database.SaveResult[] results = Database.insert(accounts);
    List<ID> accountIds = new List<ID>();
    for (Database.SaveResult result : results) {
      if (result.isSuccess()) {
        accountIds.add(result.getId());
      }
    }
    return accountIds;
  }
}

And the output does match the current types.

[
  {
    actionName: 'AccountInsertAction',
    errors: null,
    isSuccess: true,
    outputValues: { output: '0018W00002RQBBpQAP' },
    version: 1
  },
  {
    actionName: 'AccountInsertAction',
    errors: null,
    isSuccess: true,
    outputValues: { output: '0018W00002RQBBqQAP' },
    version: 1
  }
]

Maybe it's different for the standard invocable actions? Have do you have a reproducible example?

I do; for example, my action code looks something like:

public class GetPhotosAction {
  @InvocableMethod()
  public static List<Response> getPhotos() {
    List<Response> responses = new List<Response>();
    ...
    Response response = new Response();
    response.fullPhoto = 'full';
    response.smallPhoto = 'small';
    responses.add(response);
  }

  public class Response {
    @InvocableVariable(required=false)
    public String fullPhoto;

    @InvocableVariable(required=false)
    public String smallPhoto;
  }
}

and it returns:

[
	{
		"actionName": "GetPhotosAction",
		"errors": null,
		"isSuccess": true,
		"outputValues": {
			"fullPhoto": "full",
			"smallPhoto": "small"
		},
		"version": 1
	}
]

Maybe it's adding that "object" key when the list item serializes to a single value instead of an object? Not sure....there's not a lot of clear documentation.
