Reproduction steps

I have used python controller to done a stress test on my RPI sample dut (all-clusters-app) on Read-Write operation for 100000 iteration. The iteration 15819 is passed without any error but the 15820 is Failed to read the node-label attribute with the below traceback error and the next iteration 15821 is also passed without any issues.

Traceback (most recent call last):
