What is causing this error?

[JKaplan]

Folks -

I'm getting periodic errors in my log of the following form:

"12/19/2013 11:31:25 PM - Error - In SetDevTimeSinceChange:Length of argument 'String' must be greater than zero."

These show up in red in the log, and tend to recur every minute or so for a few minutes, then they seem to stop for a while. A log fragment, starting from where they began occurring (bottom of log) after restart, is below.

I have 2 scripts that run every minute, but there is no reference in them to "SetDevTimeSinceChange" - as far as I can tell, this isn't one of my functions.

Is this some sort of internal call that I don't have access to? If so, what am I likely to be calling each minute that might cause this? And why does it start up for a while then stop?

Any advice appreciated,

Jerry

Are you able to share what is in each script? You can try disabling one script to see if you can isolate which is the problem script.

[JKaplan]

Thanks, that makes sense. I was able to figure out which script, and by some trial and error found the offending call:

dc=hs.getdevicecode(name)
hs.setdevicetime dc, 0

dc was occasionally null.

The lesson here:

* SetDevTimeSinceChange is an internal function. The error message doesn't report the 'user level' call.
* Though the Help file says that the line number of the error in the program will be displayed, it is not under these circumstances.
