"Send to Power BI" is returning "Execute failed: Unknown reason" exception

[renemendes]

Hi,

I’m getting an “Execute failed: Unknown reason” exception when running “Send to Power BI” node, connected to PowerBI through an “Client/Application secret authentication”. We’ve followed the note “Work with third-party apps in Power BI - Power BI | Microsoft Learn” and granted permissions according to this note.

Thank you for any advise.

Knime Analytics Platform 4.7.1

It was not possible to identify the root cause.

After some tries, we changed the authentication mode to user/pass and the connection worked fine.

Thank you.
