Product not found, CANNOT_ADD_CART

I solve with this:
let product = await createProduct ( myProduct )
. then (( product ) => {
// product created
console . log ( “product created” , product );
productId = String ( product . _id );
})
. catch (( error ) => {
// product not created
console . error ( error )
});

setTimeout (()=>{ 
    $w ( '#shoppingCartIcon1' ). addToCart ( productId ) 
    . then (() => { 
        console . log ( "Product added" ); 
    }) 
    . **catch** (( error ) => { 
        console . log ( error ); 
    }); 
}, 2000 );
