Reconfigure the integration throws an error

[Bjsulla]

When trying to re-configure the integration in Home Assistant by pressing the cogwheel I get the following error:
"Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble".

Looking in the homeassistant log I can see the following error:
