My Integration - DLNA-Sync | Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble error when installing component

Dear somebody, I need some help. Wrote a component to synchronize play over multiple DLNA renderers. When I attempt via install HACS I get a “Config flow could not be loaded: 500 Internal Server Error Server got itself in trouble” error. I tried setting external URL in HA system but makes no difference. Tried solving this well into the morning hours. Maybe I am missing something. Any ideas? Link to the component

I have two feedback items:

• The callback-construction seems to be overdone, why not use a constant like CONFIG_SCHEMA in waqi-test/config_flow.py at 648d795c700fe9844a87083a10f69c1cdfbc13b5 · bouwew/waqi-test · GitHub ?
• You need to have a strings.json file and at least one translation file. See the above repo for examples. This file and/or the translation-file is needed to be able to show the Config-Flow user-form properly on the HA frontend.
