Application error after deploy django app on heroku

87 Views Asked by At

I have successfully built and deployed my DJANGO app on the HEROKU. During building the application collectstatic also is running smoothly. But after everything completed successfully when I tries to open my app it is showing me application error. I have adding my recent log with this question. If anyone needs more information to analyze and give the solution then I can provide that also.
