Hi Ricardo,
I created a test flow and it worked.
These are the steps:
- I added an image placeholder with a dummy image to the PPTX template.
- I have a test list in SharePoint. There is an item with an image attachment.
- I tried to add one picture to simplify the example.
imageData content is the expression:
base64(body('Get_attachment_content'))
The result:
Please try to reproduce the steps. Make sure that the attachment is an image.
Best regards,
Petr
