Getting "java.lang.RuntimeException: ZeroCode Step execution failed. Details:java.lang.NullPointerException"

Hi ,

I have upgrade the zerocode-tdd from 1.3.1 to 1.3.33.
During running the code I am getting below error

java.lang.RuntimeException: ZeroCode Step execution failed. Details:java.lang.NullPointerException

It was working perfectly and without any issue in zerocode-tdd (1.3.1).

Stack Trace:
