# Integrator fails with Unable to initialise application. Failed to validate config: data/jitsi_domain must match format "hostname"... ## Issue * After installing integrator and browsing to it by hostname, I get the following error: `Unable to initialise application. Failed to validate config: data/jitsi_domain must match format "hostname", data/jitsi_domain must be equal to constant, data/jitsi_domain must match a schema in anyOf` ## Environment * Element Enterprise Installer 2022-09.06 * Integrator ## Resolution * Add the following line to your `/integrator/integrator.yml` file: `jitsi_domain: meet.element.io` Replacing `meet.element.io` with whatever Jitsi host you would like to use. ## Root Cause There is a bug in this installer which specifies `https://` in front of the default domain and this causes the error. This will be fixed in a future installer.
