Power bi can't connect monday api

Hallo and thank you for reading this. Power Bi file, which is callinig monday api, in our company is not working anymore due authorisation issue. It used to work 3 Months ago. Now the error “Ein Web-API-Schlüssel kann nur angegeben werden, wenn ein Web-API-Schlüsselname angegeben wurde.”
Here is the connecting M Query:
Source = Web.Contents(“https://api.monday.com/v2”,
[Headers=[Authorization=“Bearer eyJhbGc…”,

I checked the token in Insomnia, it works fine. I think , the issue is on power bi side.

I would be gratefull for any help.

Kind regards,
