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

[dannyoneill]

Since the latest update I’ve been unable to configure the global settings (things like boost time). When I click the cog I get “ Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble”.

I have rebooted the HA and ensured everything is up to date.

Same for me.
When I reconfigure the gateway, it works but after a reboot the same problem appears again.

Same for me accompanied by this message in the core log.

Thanks all. Will.fix this in a release, hopefully next week.

In the meantime, if you need to fix it, edit line 120 in config_flow.py from

return WiserOptionsFlowHandler(config_entry)

To

return WiserOptionsFlowHandler()

[msp1974]

Fixed in v3.4.18
