Unable to access inner inner array from `json_parse` in a loop

Describe The Bug

Was using the GitHub API to parse release objects within arrays within an object when I was unable to access elements at array index. Then realised I couldn't access it.

To Reproduce

From duck repl:

object = json_parse "{\"obj_array\": {\"obj\": [1, 2, 3]}}"
arr_rang = range 0 ${object.obj_array.obj.length}
#i = set 1
for i in ${arr_rang}
    a00 = get_by_name object.obj_array.obj[i]
    a01 = get_by_name object.obj_array.obj[${i}]
    a02 = get_by_name ${object.obj_array.obj[i]}
    a03 = get_by_name ${object.obj_array.obj[${i}]}
    a04 = set ${object.obj_array.obj[${i}]}
    a05 = set ${object.obj_array.obj[i]}

    obj_array0 = set ${object.obj_array}
    a06 = get_by_name obj_array0.obj[i]
    a07 = get_by_name obj_array0.obj[${i}]
    a08 = get_by_name ${obj_array0.obj[i]}
    a09 = get_by_name ${obj_array0.obj[${i}]}
    a10 = set ${obj_array0.obj[${i}]}
    a11 = set ${obj_array0.obj[i]}

    obj_array1 = get_by_name object.obj_array
    a12 = get_by_name obj_array1.obj[i]
    a13 = get_by_name obj_array1.obj[${i}]
    a14 = get_by_name ${obj_array1.obj[i]}
    a15 = get_by_name ${obj_array1.obj[${i}]}
    a16 = set ${obj_array1.obj[${i}]}
    a17 = set ${obj_array1.obj[i]}

    echo i=${i} a00=${a00}, a01=${a01}, a02=${a02}, a03=${a03}, a04=${a04}, a05=${a05}, a06=${a06}, a07=${a07}, a08=${a08}, a09=${a09}, a10=${a10}, a11=${a11}, a12=${a12}, a13=${a13}, a14=${a14}, a15=${a15}, a16=${a16}, a16=${a16}, a17=${a17}
end

However this works just fine:

v = get_by_name object.obj_array.obj[1]
echo v=${v}

@SamuelMarks i can't see any issue

object = json_parse "{\"obj_array\": {\"obj\": [1, 2, 3]}}"
echo ${object.obj_array.length}

echo ${object.obj_array.obj.length}
count = set ${object.obj_array.obj.length}
echo count: ${count}
range = range 0 ${count}
for i in ${range}
    echo index: ${i}
    value = get_by_name object.obj_array.obj[${i}]
    echo value: ${value}
end

echo direct access: ${object.obj_array.obj[1]}

jsonstring = json_encode object
echo ${jsonstring}

outputs:
