I've been tasked with creating a website using both HTML and Python CGI. I've ran into many issues however managed to solve them all and got the HTML and CGI to work on the inbuilt python webserver using the command: python3 -m http.server --cgi -b 127.0.0.1 8000
However, this project is being marked on my universities own webserver, and when I run the code from that webserver, Once the script attempts to open the CGI file, I'm met with this error:Error Referred from: https://project.cs.cf.ac.uk/LootsSG/part202/ HTTP status: 500
Your code returned an error: End of script output before headers: hello_get.py
This really confuses me as I can't figure out what that error means, or why it would only work on particular servers.
