The Swagger docs are not accessible via the application's Heroku URL.

The API is correctly bound to all network interfaces (as denoted by 0.0.0.0) whereas the swagger docs are bound to 127.0.0.1 which makes them inaccessible from anywhere other than localhost. I.e. Only accessible on the same machine as the R process running the plumber application.

This issue is caused by the host changing logic as reported in rstudio/plumber#813.

When deploying to Heroku, whether using the one-push button or running the commands manually, opening the app shows an application error, and the log shows this error. Do you know what might be causing the problem?
