[OpenSIPS-Users] Parsing null parameter

[M.Khaled W Chehab]

Hi,

 

I got the below error while $var(prefix) = null  ,how to avoid this error 

$var(prefix) = $(avp(gw_attrs){csv.value,1});

 

ERROR:core:tr_eval_csv: Index out of bounds

ERROR:core:do_assign: no value in right expression

ERROR:core:do_assign: error at line: 877

 

Regards
