"Read Prim Attribute" Node in Action Graph Not Returning Values

In my current setup, I am using multiple Read Prim Attribute nodes to get data from my model. However, I’ve noticed that only the first two nodes are successfully returning the correct values. Whenever I add a third or any additional Read Prim Attribute nodes, they fail to return any value (returning null or zero), even if I configure them the same way as the functional ones.

Is there a specific execution flow/caching issue that might cause subsequent nodes to fail? How can I troubleshoot why these additional nodes are not returning values?

Could you try upgrading to the latest Isaac Sim 6.0.0 OSS DP and see if the issue persists?
