asana tasks api does not work for GET /tasks GET /workspaces/workspace_id/tasks but for GET /projects/project_id
===

My query were these:

https://app.asana.com/api/1.0/tasks
But I have this error instead: "Must specify exactly one of project, tag, or workspace"

When I try out for the workspace with this:
https://app.asana.com/api/1.0/workspaces/workspace_id/tasks
I have this error: "assignee: Missing input"

However, I will get a list of tasks if i use the projects instead...

Please advice.
