Exception Value: Failed loading libasound.so.2: libasound.so.2: cannot open shared object file: No s-CodePudding

I made a drowsiness detector for driving using django. I tried deploying it on heroku and everything seems to be working fine except as soon as I try to open the camera, I get the error:

Exception Value:    
Failed loading libasound.so.2: libasound.so.2: cannot open shared object file: No such file or directory

All the other pages are working fine, you can try it out here (login credentials username: temp password: Temp@123). As soon as you click on Start Driving it throws this exception. The app is working fine in localhost. Please help!
