I am following the documentation https://developers.podio.com/doc/applications and the given models from the SDK.
Im trying to add a new app to an existing app reference like so:
$attributes = array(
"referenced_apps" => array(ref_app_id1 , ref_app_id2)
);
PodioAppField::update( 123 , 'my_external_id' ,array (
"settings" => $attributes
));
But will receive the following error
Uncaught PodioNotFoundError: "No matching operation could be found. The path '/app/123/field/my_external_id' was not found.."
My app_id and external_id are correct.
TIA
