Power Bi Service Error - Failed to update data source credentials: ADO.NET: python.exe not found.

Hi!

I have been trying to schedule a refresh using Power BI Service for my Dataset that contains Python scripts. Scripts to get data from a Soap Web Service. I have set a personal gateway with my machine.

When I try to schedule the refresh, I first receive this message error: Your data source can't be refreshed because the credentials are invalid. Please update your credentials and try again.

When I go to edit credentials and set my privacy to none or public, I got the following error:

Failed to update data source credentials: ADO.NET: python.exe not found. python.exe was not found in the specified directory. Please make sure you have a complete Python installation.

Request ID:	ec6c6677-073f-3537-d466-0ba573984cbb
Status code:	400

I have Python installed in my machine and the refresh works fine in my PBI Desktop. My PBI Desktop has the correct python home directory. The same I use in my visual code studio. It is AppData\Local\Microsoft\WindowsApps

I appreciate any help.

Hi @Mp1977 ,

Which kind of gateway did you use in your scenario? As the online document , When you publish a Power BI report with Python scripts to the service, these scripts will also be executed when your data is refreshed through the on-premises data gateway in personal mode (personal gateway).
