Bug when divide by 0 with AMP engine

[frankzhang]

Is this a known bug with AMP engine? (I am using version 2021.2.1.35394)

It is incorrect only when you tick the box under runtime to use AMP engine.

My formulas:

Strange output:

 Looks like it used value in the row-1 from no where.

@frankzhang ,

 it looks scary 🎃 to me.  I'll tag @gfilla  and see if it's 📰 to him.

Yep. It is scary for me as well. I have already stopped using AMP engine in all my workflows. For my particular example, it is fine if it returns NULL, 0 or error. It shouldn't return value from other rows.

Hi @frankzhang - thanks for reporting this issue and for using AMP! 

This is a new issue, we were able to reproduce this and have this logged internally as a defect.  

Thank you,

Greg
