Can't add the integration "Config flow could not be loaded: {"message":"Invalid handler specified"} "

[gl01bxg2003]

I have had problems with indego integration for a very long time. I noticed today that an update came.
I had previously removed the device from my device list in HA trying to fix the integration on the old version.
I updated the integration in HACS and when I am trying to add device I get this error message: Config flow could not be loaded: {"message":"Invalid handler specified"}

I have installed the browser extension indicated in the description, I have tried removing the integration from HACS, redownloading, installing., resart of the PC I am working on. HA Serve restart..
Can you please help me?

Good Morning,
Do you have any further Logs for this failure ?
At which point of installation/configuration do you get the error ?

In the past there were similar problems because of a wrong vacuum.py file but it was fixed some releases ago so this should not be the problem. The other possible solution ist also described in #270 , #277 and #275 . In all these cases the error message was also "Config flow could not be loaded: {"message":"Invalid handler specified"} " and was fixed by changing the user agent during configuration of the integration. Have you already tried this ?

Regards,
