Error: unable to deal with unit: cm

When I pilot my experiment on Pavlovia, I have this error:

But I did not use any cm unit in my program. I used only norm unit. Does anyone know how to deal with this error?

This error can occur when you use cm units in a text stimulus (in the builder, these can be found in the advanced tab). While you said you only use norm units, could it be that this accidentally happened with a text stimulus somewhere?
