Mod_external_services

hello good evening I would like to know if someone has used the external_services module I want to use this to activate turn in jvb in jitsi in the normal installation with apt get, I am currently in the configuration file lua I would like to know if external_services is correctly configurator since I put the data from my turn server and in external_service_secret I also put the secret key that is configured on my turn server, is this data correct? In which muc_mapper_domain_base is currently the host of the server where my installation is hosted, but is this correct or should my server’s host turn? since with this configuration I have the following error when starting jvb

Which prosody version is this?
