LoanApplication la = new LoanApplication();
la.setCreditCheckOk((Boolean) execution.getVariable("creditCheckOk"));
la.setCustomerName((String) execution.getVariable("name"));
la.setIncome((Long) execution.getVariable("income"));
la.setRequestedAmount((Long) execution.getVariable("loanAmount"));
la.setEmailAddress((String) execution.getVariable("emailAddress"));

Hi,

Are you testing this with Activiti 5.12.1? The reason why I'm asking this is because we changed the automatic promotion of script variables to execution variables.

Best regards,

Ok, please read the user guide section about script tasks (http://www.activiti.org/userguide/index.html#bpmnScriptTask)
You should explicitly set the variable now like:

<blockcode>
<script>
def scriptVar = "test123"
execution.setVariable("myVar", scriptVar)
</script>
</blockcode>

That should prevent the nullpointer from being thrown.

Best regards,
