Question about planting san pedro cuttings

[Uranium]

I have a 3 inch san pedro cutting.
The cut is not angled.
It was perfectly cut with zero angle, like the cactus was placed into a guillotine.
After it dried, the center of the wound went inwards a little, and now a small bowl-shaped hollow space is present at the bottom of the cactus.
If I plant it, will this cause water to accommodate there and rot the plant?
If so, what is the solution?

I don't see how the bowl-shaped hollow space could retain water. IMO just plant it and all will be fine.

After all, it's better than not planting it, right?

You need to wait until that thing puts out a few small roots so its ready to take up water. If you plant it like that and it gets too much water it will rot and be no good. Keep it stored in an upright position as well or else it will start growing funny. And make sure it gets a little bit of light, preferably in the shade, so it doesnt start growing skinny & white.

Cuttings that small dont always make it so good luck.
