Hi, I am using JSON module and when i call json_get_field from kamailio.cfg, xlog("L_INFO", "JSON string: $var(json)\n"); json_get_field($var(json), "from_number", "$var(from)"); i get following warning, INFO: <script>: JSON string: {"from_number":"49XXXXXXXX","to_number":"49XXXXXXXX","domain":" sip.mydomain.com","from_name":"John","timestamp":1414095386.7094} WARNING: json [json_mod.c:86]: fixup_get_field_free(): free function has not been defined for spve While the code works fine, but this warning just gives me worries that there may be a memory leak here. Can you guys confirm if i can ignore this warning when this code goes to production? Thank you.
