Some syntax errors in your zscript. check the line# as indicated in the exception trace.

But the application works without a problem about six days. The seventh day gave this problem, so I think there's not a problem in my zscript.

Looks like it's a runtime error. You have a nullpointer exception. One of your runtime values is NULL which you haven't expected in your code.

unknown error: null : at Line: 199
