ID 585036 - Creating a locator type prim in a PrimitiveCreate node causes an error in the terminal on scene graph expansion

Problem summary:

When expanding a scene graph that contains a locator created via a PrimitiveCreate node, the following error is output to the terminal:

`Error loading primvar 'geometry.arbitrary.st' from '/root/world/geo/primitive2': Arbitrary output attrs are not supported for geometry type 'locator'.`

This error is continuously spammed in the terminal when transforming the locator while the scene graph is expanded.

Steps to reproduce:

1. Create a PrimitiveCreate node
2. Enable the edit and view flags on the node
3. In the Node's parameters, change the _type_ to locator
4. Expand the scene graph so that the prim is visible in the viewer tab

Expected behaviour:

Locator prim is created, and no errors are present in Katana

Actual behaviour:

Locator prim is created, but an error is printed in the terminal.

Workaround:

No known workaround.
