Hi @winston_smyth ,
Could you please share a screenshot more about your flow's configuration?
Could you please show more details about the error message within your flow?
Based on the issue that you mentioned, I have made a test, and the issue is confirmed on my side. Actually, it is an known limit with images stored in SP Site -- The images stored in SP Site need authentication to access them.
Currently, there is no way to grant the access permission of a SP Site to a Face API connector in Power Automate. If you would like this feature to be added in Power Automate, please submit an idea to Power Automate Ideas Forum:

As an alternative solution, you could store the image file into a Shares folder without authentication to access, then pass the URL of the image file to the "Detect faces" action of your Face API connector, check if the issue is solved.
Note: The image URL must be one of the following format:
