I am getting the error 
These are fields I am trying to add with images or PDF.

How do I set this up in ArcGIS Pro so that when I add this feature service I can import it to Survey123. These features were original "text" in my feature layer just so I could get them imported into Survey123. After in Survey123 I changed them to image. I then tried to publish it and then the error above was displayed. Send me a video on how to do it I can not understand the text responses very well without a reference video. Thank you.
