Schedule refresh of Python script in Power BI Service
Good Afternoon
I would like to set up a scheduled refresh of a Python script in the Power BI Service but I am experiencing some issues. The script that I have written logs in to a website (using credentials saved in another .py file) and downloads a file. I have installed the latest version of the personal gateway on my computer and can confirm that this is where python is installed and where the script/Power BI Desktop files are stored. I have also checked that the privacy setting of the data source is set to public.
When I try to set up a scheduled refresh in the Service it says that my credentials are invalid. When I click on 'edit credentials' I only get presented with the authentication method = WindowsWithoutImpersonation which I haven't come across before. If I try to sign in using this method, I get the following error message:
"Failed to update data source credentials: ADO.NET: Failed to find or load the registered .Net Framework Data Provider"
The Python script runs and refreshes fine in the Power BI Desktop file but I am wondering whether the embedded credentials are causing an issue in the Service. Has anyone experienced similar issues? Any help or advice would be much appreciated.
Thanks
Claire
Hi Claire4Green
I found it has been added as a known issue:
Power BI customers using Python or R visuals together with May release of the Power BI Personal Gateway may see the following error message when trying to refresh: “ADO.NET: Failed to find or load the registered .Net Framework Data Provider”. As a workaround users may revert to the April release of the Power BI Personal Gateway. Engineers are working on a fix and expect it to be deployed by end-of-day 06/06/2020.

Try to configure the gateway as default mode, not personal mode. And see how it is working

Appreciate with a kudos 🙂nandukrishnavs thank you but how do I set the gateway to default? There aren't any options against my personal gateway.
Download the gateway setup file and install it, it will provide two options.
- On-premises data gateway
- On-premises data gateway (personal mode)
Choose 1st one.
Follow the steps https://docs.microsoft.com/en-us/data-integration/gateway/service-gateway-install#download-and-install-a-standard-gateway
Then you can add your data source in the gateway cluster.follow this https://docs.microsoft.com/en-us/data-integration/gateway/service-gateway-manage

Hi Claire4Green
The python script is supported on the personal gateway, kindly refer to the troubleshooting document for more hints:
Further more, It might be related to the .NET Framework. Please re-installed .NET framework and restarted the server for a test.
Failed to find or load the registered .Net Framework Data Provider
and here is a simiar post for you as a reference.
Hi v-diye-msft thanks for your suggestions. I have unistalled and reinstalled .NET Framework and now have version 4.8 but unfortunately this hasn't resolved my credentials issue. When I go to edit my credentials, the only authentication it presents me with is WindowsWithoutImpersonation and the error is still "Failed to update data source credentials: ADO.NET: Failed to find or load the registered .Net Framework Data Provider". Do you know what else might be causing the issue? Thanks!
Is your gateway the latest version? Probably quick check if your gateway machine run out of disk/memory?

v-diye-msft thanks for letting me know. I have now downloaded the April version of the personal gateway and have been able to successfully schedule a refresh via the service. Thanks for your help!
June version of Power BI Gateway (personal mode) has been released. This version resolves the ADO.NET issue for Python datasource.
I've downloaded and it connects with no issues.
