Python script as a data source in Power BI Service

Hello!

I have created a dashboard which uses a Python script a s a data source (it makes requests to google analytics API). Python script works fine at PBI Desktop.

As far as I understood in order to refresh data in Power Bi Service on a regular basis I need to configure a On-premises data gateway (personal mode). I did that using this instructions https://docs.microsoft.com/en-us/data-integration/gateway/service-gateway-install

So first I installed and configured a standard gateway (named powerbi_python) and then a personal mode gateway. They are installed on the same machine as my pbix file and Python.

I am confused what should I do next. I want to add a new data source under this gateway but Python script isn’t on the list:

I go to settings -> datasets and there is a message saying the gateway isn’t configured correctly and an error message Extension{"extensionDataSourceKind":"Python","extensionDataSourcePath":"Python»} unable to add to gateway. Lower is another info saying the personal gateway is not installed although I did install it. Sorry the screen is in Russian.

What am I missing here?
