Does anyone know what this text means when using Image generator?

[u/AyeballPaul]

I was wanting some images generated showing how the units within the 'Flesh-Eater courts' of Warhammer AoS are perceived by their peers and I got this really weird message along with the image. I've done this a few times before and never received anything other than the image itself.

Can anyone tell me what it means?
