Awk conditional inside bash while loop

I am trying to make a while loop that goes through a text file line by line, tests whether a field is blank using Awk, then does an action based on whether that condition is true or false.

The input file is this:

$ cat testarr.csv
cilantro,lamb,oranges
basil,,pears
sage,chicken,apples
oregano,,bananas
tumeric,turkey,plums
pepper,,guavas
allspice,goose,mangos

My expected output is:

this_is_one_iteration
ItIsNotBlank
this_is_one_iteration
ItIsBlank
this_is_one_iteration
ItIsNotBlank
this_is_one_iteration
ItIsBlank
this_is_one_iteration
ItIsNotBlank
this_is_one_iteration
ItIsBlank
this_is_one_iteration
ItIsNotBlank

based on Using 'if' within a 'while' loop in Bash and similar threads, I did this:

#!/bin/bash

error=ItIsBlank
success=ItIsNotBlank
while read LINE; do
echo this_is_one_iteration
QZ1=$(awk -F "," '{print (!$2)}')
if [[ $QZ1==0 ]] ; then
    echo $error
else
    echo $success
fi
done < testarr.csv

which gave me:

$ bash testloop.sh
this_is_one_iteration
ItIsBlank

So it doesn't even seem to be iterating through the file. However, if I take out the conditional, it iterates just fine.

#!/bin/bash

error=ItIsBlank
success=ItIsNotBlank
while read LINE; do
echo this_is_one_iteration
done < testarr.csv

gives:

$ bash testloop.sh
this_is_one_iteration
this_is_one_iteration
this_is_one_iteration
this_is_one_iteration
this_is_one_iteration
this_is_one_iteration
this_is_one_iteration

also, the conditional seems to work OK when not using awk:

QZ1=test
while read LINE; do
echo this_is_one_iteration
if [[ $QZ1=="test" ]] ; then
    echo It_worked
fi
done < testarr.csv

Gives me:

$ bash testloop.sh
this_is_one_iteration
It_worked
this_is_one_iteration
It_worked
this_is_one_iteration
It_worked
this_is_one_iteration
It_worked
this_is_one_iteration
It_worked
this_is_one_iteration
It_worked
this_is_one_iteration
It_worked
