Converting SIP extensions to PJSIP with fwconsole damage EPM module

I’ve two pbxs where i restored a full FPBX15 backup onto a fresh FPBX17 Debian vm.
All was right but not EPM module (and other activities related to extensions). If i try to do some mods i always obtain an error like:

Whoops \ Exception \ ErrorException (E_WARNING)

Undefined array key “user”

/var/www/html/admin/modules/endpoint/EndpointGrandstream.class.php

I’ve already tried to uninstall and reinstall EPM (latest version 17.0.1.87). Tried to rollback to previous version 17.0.1.84, nothing changed. Also tried rolling back to 17.0.1.80; no success.

Problem was specific on Grandstream phones inside EPM module. So title is not realistic.

It was present both after a restore or in a new fresh Debian and fpbx17 install. So it was not related backup/restore but only abount EPM module.

It has been solved thanks to Sangoma support with edge module 17.1.0.93 published yesterday.
