Cannot connect my AWS EC2 Instance to my GitHub Webhook - amazon-web-services

Question

How I should be able to add two port numbers to my new Inbound Rule for the GitHub webhook I created with the Type being Custom TCP, the Protocol being TCP, the Port Range being 8080, and most importantly, the Source being Anywhere with two custom source ports of 0.0.0.0/0 and ::/0 which is seen below in a screenshot of the specific reference from the course itself:
Then when I try and do the same for my EC2 Instance's Inbound Rules, I can only add one source for the port range of 8080 as seen below...
As a result, I cannot have both 0.0.0.0/0 and ::/0 connected to port range 8080 simultaneously as seen again below for clarification
When I try and do so, I am forced into creating two separate Inbound Rules, both being Custom TCP, Port Range 8080, and the Source of each directing to 0.0.0.0/0 and ::/0 independent of each other, not under one unified Inbound Rule
As a result, I believe this is why I am not capable of creating an established webhook from my GitHub repo to my AWS EC2 instance.
For more clarification, the course itself is walking me through how to properly setup a webhook from GitHub to my newly created AWS EC2 in conjunction with the directions here in the very detailed and well-written Strapi documentation, however, after I have followed these directions and have properly created a webhook.js file within my NodeWebHooks file of my root SSH, this is the error I get when I try to establish the connection which is most probably because of the inability to setup my Inbound Rule properly per the additional directive of the course.
As I still try and attempt to follow the documentation with two separate Inbound Rules from Port 8080 with a source of 0.0.0.0/0 and ::/0 respectively, in accordance with the guide, in my root SSH I enter:
echo $PATH
and copy and paste the path within the file of:
sudo nano /etc/systemd/system/webhook.service
in the proper script as below:
or as code, it is:
[Unit]
Description=Github webhook
After=network.target
[Service]
Environment=PATH=/home/ubuntu/.npm-global/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
Type=simple
User=ubuntu
ExecStart=/usr/bin/nodejs /home/ubuntu/NodeWebHooks/webhook.sj
Restart=on-failure
[Install]
WantedBy=multi-user.target
Then when I save and exit from that file, in order to enable it, I do:
sudo systemctl enable webhook.service
and receive the appropriate desired response of "Created symlink ... etc..." where it clarifies that a webhook.service has been created.
However, then when I run the following:
sudo systemctl start webhook
sudo systemctl status webhook
I get an error which states the following:
or alternatively, as code it is the following response:
ubuntu#ip-172-31-3-74:~$ sudo systemctl start webhook
ubuntu#ip-172-31-3-74:~$ sudo systemctl status webhook

The issue is most likely that the webhook.service file references under [Service]: home/ubuntu/NodeWebHooks/webhook.sj, when it is probably named /home/ubuntu/NodeWebHooks/webhook.js. It's the little things that get you!
