Can't add Shelly

Hi. I was trying to add a Shelly rgbw 2 device to my assistant. But it gives such an error." Failed to load configuration wizard: 500 Internal Server Error Server got itself in trouble"
Shelly works in its native app. I changed all the settings for the connection but nothing. Does anyone have thoughts?

the box icon next to your shelly integration looks like its fron HACS. try using official Shelly integration.
