How to use Login Information Parser Plugin?

I am getting the following error when I try to run the process model:
"There is a problem with task “Import Login Information” in the process “POC Get Login Details”. java.lang.NullPointerException ,
An error occurred in executing an Activity Class. "

We have also seen this issue while using the functions to give date like today() or any other like this. But it works fine if we select the date. We have tried to understand the format and if you see in expression editor, the selected date appears in text enclosed with "". So we used "today()" in expression editor and it works for us. Just try it and let me know if this works. But other functions doesnt seem to be working.
