I have found an issue while updating the Flickr plugin to use Copula:
In ApiSource.php->read():
uri->query = is set to be a string a=xxx&b=yyyy
$model->request['uri']['query'] = $this->_buildQuery($conditions);
However in Network->http->httpSocketOath.php
Line 176 block:
if (isset($request['uri']['query'])) {
$requestParams =array_merge($requestParams,$this->assocToNumericNameValue($request['uri']['query']));
}
expects uri->query to be an Array since it calls assocToNumericNameValue,
I fixed for my purposes by setting:
$model->request['uri']['query'] = $conditions;
