I have developed a website that scrapes data from a webpage, processes it, saves it into an Excel file, and then sends the file as an attachment. On my local machine, the whole process completes successfully in around 45 to 50 seconds without any errors. However, when I deploy the application on Heroku, I encounter a "Request timeout" error (H12) after 30 seconds of processing. Despite the error, the code doesn't throw any exceptions on my local machine.

How can I resolve this "Request timeout" error (H12) on Heroku and ensure the application completes the process successfully within the specified time frame?
