Why can't my script write new files?

My script is:

#!/bin/bash
for n in {1..10}; do
    echo $n
    dd if=/dev/urandom bs=1 count=$(( RANDOM + 1024 )) > /testingscript/file${n}.txt
done

I would like it to create a file in the /testingscript directory with the name file'n'.txt, where n is the number of the file. Instead, I am getting this error:

1
./create.sh: line 5: /testingscript/file1.txt: No such file or directory
2
./create.sh: line 5: /testingscript/file2.txt: No such file or directory
3
./create.sh: line 5: /testingscript/file3.txt: No such file or directory
4
./create.sh: line 5: /testingscript/file4.txt: No such file or directory
5
./create.sh: line 5: /testingscript/file5.txt: No such file or directory
6
./create.sh: line 5: /testingscript/file6.txt: No such file or directory
7
./create.sh: line 5: /testingscript/file7.txt: No such file or directory
8
./create.sh: line 5: /testingscript/file8.txt: No such file or directory
9
./create.sh: line 5: /testingscript/file9.txt: No such file or directory
10
./create.sh: line 5: /testingscript/file10.txt: No such file or directory

What am I doing wrong causing my script to not write new files? I should add that this script worked perfectly as intended on my VM running Ubuntu 16.04. I am now attempting to run this on a physical computer running Ubuntu 18.04.

There is no directory

 /testingscript

If you want to create files in the current directories folder 

yourCurrentDir/testingscript

You should remove the first "/" and use testingscript/file${n}.txt

#!/bin/bash

for n in {1..10}; do
        echo $n
        dd if=/dev/urandom bs=1 count=$(( RANDOM + 1024 )) > testingscript/file${n}.txt
done

To check if there is a directory /testingscript

ls / | grep testingscript

The expected output is 

testingscript
