Lametric time configuration

Configuration
1

My lametric time has been auto discovered and I get the prompt to configure.
However if trying I just get the error message "Error

Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble"

Any help with this would be much appreciated.
