Hello, The issue is fixed after reverting this commit. Regards, Nicolas. De : Daniel-Constantin Mierla <miconda(a)gmail.com> Envoyé : mardi 9 novembre 2021 11:41 Hello, there was a recent change trying to catch the case when setting the variable to a null string (it was reported to bug tracker as a side effect of operations done by other module, maybe lost?!?): * https://github.com/kamailio/kamailio/commit/6eb67eaa4fc27d1eb7da7b2b674ffe8… Can you try to revert and see if it fixes? Right now I don't have the time to test. Cheers, Daniel On 09.11.21 10:10, Chaigneau, Nicolas wrote: Hello, I’ve just built Kamailio from the master.

Should be now fixed by a new commit. You can test again with a fresh master branch clone.
