I'm consuming the Conduit API to retrieve tasks by author. The request parameters is:
```
var api_params = {
"api.token": "api-the_token",
"authorPHIDs": {"ownerPHID":"PHID-USER-the_user_hash"}
}
```
I'm get the message: //Argument 1 passed to ManiphestTaskQuery::withAuthors() must be of the type array, string given//
The json result is:
```
{"result":null,"error_code":"ERR-CONDUIT-CORE","error_info":"Argument 1 passed to ManiphestTaskQuery::withAuthors() must be of the type array, string given, called in \/core\/lib\/phabricator\/src\/applications\/maniphest\/conduit\/ManiphestQueryConduitAPIMethod.php on line 77 and defined"}
```
