If the cfg_schedule is not an input in the node, remake the node so that it is or it errors out. It doesn't update automatically on older workflows.

HI Kijai,
I have the same problem. What do you mean by - Remake the Node? Im a non-developer.

Literally remove the node and add it again. Or right click on it and use the "fix" option to recreate it.
