solved! If I move the following code:
let pizzaImg=pizzaList[0].pizzaPic
$w('#image1').src=pizzaImg
$w('#image1').show
before (and not after as it was originally)
$w('#menu').rows=pizzaList
$w('#menu').show
console.log('frontend')
console.log(pizzaList[0].pizzaPic)
it works. I don’t understand reason why. but works
