Hi Bogdan,
I'm not seeing any other related error msg prior to this. I'm calling this test
in request route for a REGISTER request. Before the error pops up I could see
the received msg successfully parse by opensips and can see value of To uri

Hi Pasan,
It should be fine if $tu would translate to NULL. The script handles this
case. But I'm afraid you have something else there, like another deeper error
that prevents the $tu variable to be evaluated.
Do you see any other errors before the mentioned ones ? what is the type of
route where you do the test ?

Hi Guys,
I have a check for NULL for $tu var in the script, But when the value is
missing I'm getting the following error.
ERROR:core:comp_scriptvar: cannot get left var value
WARNING:core:do_action: error in expression at /etc/opensips/opensips.cfg:806
and line 806 contains following.
if ( $tu != NULL ) {
remove("location","$tu");
}
any suggestion on how to test for NULL values without getting above error.
I'm using opensips 2.3.5
