@Hainn From your screen, it look like you are trying to do some AI stuff. Please explain a little what you are trying to do. Which Dataverse table are you trying to add a column to?

Background : I have some picture and try to count number of Brush head from it.


I did build  objective as steps : AI builder/ build =>Object Detection => public =>

I think that error relate to data source. I don't know how to repair. just try.

but it still error as #2

@CNT  sorry for bothering you, 

 I did post topic in AI Builder.

But I found that it was remarked as spam.

May be I not sure the rules or new member can not post new topic ?

@Hainn I'm not aware of any such limitations. Just give it one more try here,
