Recently upgraded to Home Assistant 0.88.1 and can no longer login to the webui. All other services seem to be working fine (automation, integration, etc).
This error is displayed in the UI:
Logging in with Home Assistant Local. Error: Message format incorrect: required key not provided @ data['redirect_uri']
Error from log:
ERROR (MainThread) [homeassistant.components.http.data_validator] Data does not match schema: required key not provided @ data['redirect_uri']
Anyone have suggestion on how to fix this. Nothing turned up the change log about authentication changes in 88.x.
