7 months ago @cloudbackenddev i have seen this error after jackson-databind version updated to 2.13.5. Please override ScenarioSpec.java and Step.java with below changes - it should solve null pointer exception issue.
ScenarioSpec.java from this.steps = steps; ----> this.steps = steps == null ? new ArrayList<>() : steps;
Step.java from this.assertions = assertions.isNull() ? verify : assertions; ----> this.assertions = (assertions != null && assertions.isNull()) ? verify : assertions;
Spring boot versions post 2.4.2 is not compatible with zerocode. I always get a null pointer exception. For eg I used version 2.7.6 and it resulted in the following error trace. If i switch the repo to lower version of spring it is working. Not clear fromt he error why it is failing. Is it due to mismatched jackson dependencies between spring and zerocode?
I tried to use 1.3.27 and also 1.3.33. Iam facing the same issue
