Function is not mapped on [auth kemi](https://kamailio.org/docs/tutorials/5.3.x/kamailio-kemi-framework/mod… so we tried to use [modf](https://kamailio.org/docs/tutorials/5.3.x/kamailio-kemi-framework/kem… but we have every time this log ``` app_lua [app_lua_api.c:1725]: sr_kemi_lua_modf(): function 'www_challenge' has fixup - cannot be used ``` We tried this call to the method on lua script ``` KSR.x.modf("www_challenge", realm, 1); ``` The question is: are we calling method on a bad way or is not possible to call www_challenge method by kemi lua ? <!-- Explain what you did, what you expected to happen, and what actually happened. --> ### Troubleshooting #### Reproduction <!-- If the issue can be reproduced, describe how it can be done. --> #### Debugging Data <!-- If you got a core dump, use gdb to extract troubleshooting data - full backtrace, local variables and the list of the code at the issue location. gdb /path/to/kamailio /path/to/corefile bt full info locals list If you are familiar with gdb, feel free to attach more of what you consider to be relevant. --> ``` (paste your debugging data here) ``` #### Log Messages <!-- Check the syslog file and if there are relevant log messages printed by Kamailio, add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site). --> ``` (paste your log messages here) ``` #### SIP Traffic <!-- If the issue is exposed by processing specific SIP messages, grab them with ngrep or save in a pcap file, then add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site). --> ``` (paste your sip traffic here) ``` ### Possible Solutions <!-- If you found a solution or workaround for the issue, describe it.
