The template descriptor does not contain data required for scale-invariant matching

[PULSE.Wannabe]

I am a beginner, I'm making a key pattern matching with labview

The problem is when I turn on the scale function from the IMAQ Setup Match Geometric Pattern 2 - match mode , it says the template descriptor does not contain data required for scale-invariant matching ,

here is the function in vision assistant

I'm not really good at this , thanks in advance , file as attached below
