How can I assign a Task to a Guest user? - podio

Question

I am attempting to assign a Task using the Podio API to a guest user.
I can do this easily through the Podio Web Interface (I do it all the time) but why can't I do this with the API?
Here is my basic code:
$resp_profiles[] = array(
'type' => 'profile',
'id' => 4346424);
PodioTask::create(array(
'text' => $subTitle,
'description' => $subTitle,
'private' => false,
'due_on' => $task_due_date->format('Y-m-d H:i:s'),
'responsible' => $resp_profiles,
));
Here is the error I get:
Fatal error: Uncaught PodioForbiddenError:
"Must be at least light on user 4346424 to perform this operation"
Request URL: http://api.podio.com/task/

From Podio help page: https://help.podio.com/hc/en-us/articles/201019898-Member-roles-in-workspaces
Guests are users that have been invited to selected items using the
share item tool. They can edit and comment these specific items, but
cannot see anything else within the workspace, such as the full list
of members, other information in the app, or other apps in the same
workspace.
Have you tried changing role to 'Light' ?
That will also explain error message: Must be at least light on user 4346424 to perform this operation
You cannot assign a task to guest user profile even from frontend. It might be a bit confusing because you can assign task to user using mail user identifier, but that is restricted to Podio highly trusted partners only.
