                                                                                  indeed a very weird error I am dealing with. Weird because the same project is working fine when I am running it on localhost in pyCharm, however, when I uploaded all the files to EC2 server. I got the following error.

                                                                                  The project is running fine so I am able to host the application however when I send a post request I get HTTP ERROR CODE 500 as a response and following error in the console.

                                                                                  If someone could help me rectify this, I would be grateful
