I am trying to make a fullstack application where by backend creates an mp4 video, then sends it to the frontend.

However, my backend successfully creates the video with correct audio, and I see the file being created on the backend, but then when my frontend receives the api request and plays the video, there doesn’t appear to be any audio. Does anyone know why the audio wouldn’t carry over to the frontend. I can play the video file from the backend directory and it works fine. I am using react to render the video to the screen and Django backend to send out the video itself.
