How to track down this exception

CDriver · November 21, 2018, 10:15pm

Folks,

I have a rather annoying exception which is appearing in the logs.
I cannot for the life of me find what is causing this. I don’t actually know what rule is triggering it.
It mostly happens alongside some welcome rules I have but I’ve commented them all out and still get this.

Anything special I can do or add to see which rule it is?

thanks
C

Somewhere you have a Procedures lambda, most like in a Timer.

Inside this lambda you have a <= operation. The exception is telling you that one side of the <= operation doesn’t support the <= operation. I’d guess that there is a variable that is null or an Item whose state is NULL.

vzorglub · November 22, 2018, 4:45am

And the variable in named: vol

CDriver · November 22, 2018, 6:40am

@rlkoshak, yup, got all that. In many places Been chasing them down but as I can’t work out where and what throws the exception I’ve been struggling to solve it.

@vzorglub ! That’s it!

I did not see the var vol! I now where that is now
Embarrassing that I did not read line to of the exception

thanks both!

rlkoshak · November 22, 2018, 7:21am

I didn’t either.

When I saw @vzorglub’s post I was like “Wait, what?” Sure enough it was right there. Good catch!

CDriver · November 22, 2018, 7:53am

Far to many times in my career have I been stuck on a problem. Finally cry out for help and one of the other guys or gals walk over and immediately say “there’s your problem” and walk away. They don’t even sit down!

Fresh eyes

vzorglub · November 22, 2018, 7:57am

I couldn’t sit down. I was working
I saw the thread before and I couldn’t answer because I was on my phone.
I marked the thread as watching because I want to reply when at home, half hoping that someone else would pick it up before so you would have an answer earlier.
Then @rlkoshak replied and from my phone I could write that small post!!!
You’re welcome
