[sr-dev] [kamailio/kamailio] uri.param and param.value error when last character is delimiter (#1991)

### Description I am trying to extract a parameter with transformations from an URI in Kamailio 5.2.3, Centos 7 The problem occurs with uri.param and param.value transformation when the last character of the input string is the separator. I such case an error is thrown and no parameter value can be received. The code should be fixed so that empty parameters are simply skipped. # Example $var(someuri) = "sip:2660926042@23.26.41.95:65485;app-id=7537263245341023;"; # error with uri.param $var(appid) = $(var(someuri){uri.param,app-id}); # another error with param.value $var(appid) = $(var(someuri){param.value,app-id}); error: "Param name missing after ;" The problem is here where an error is thrown for zero length params: https://github.com/kamailio/kamailio/blob/master/src/core/parser/parse_para… if(_s->len == 0) { LM_ERR("Param name missing after %c\n", separator); goto error; } -- You are receiving this because you are subscribed to this thread.
