CustomFieldsBase#findByWorkspace(String) has an incorrect return type.

[csnemeti]

The code for the method is like this:

public ItemRequest<CustomField> findByWorkspace(String workspace) {
   String path = String.format("/workspaces/%s/custom_fields", new Object[]{workspace});
   String path = String.format("/workspaces/%s/custom_fields", new Object[]{workspace});
   return new ItemRequest(this, CustomField.class, path, "GET");

}

Since you return ALL CustomField objects from a workspace the method should return CollectionRequest<CustomField> not a single item.
Calling the method generates Exception...

Right you are, this does seem like a bug.

Since this is generated by our documentation and client library tool, I think the correct fix is to set collection: true in https://github.com/Asana/asana-api-meta/blob/master/src/resources/custom_fields.yaml on this endpoint. We'll get a fix in on our next round of client library / documentation updates. Thanks!
