heroku[web.1]: Process exited with status 255
Not just in Heroku, but when I run my Play app with a user whose name is different than the default user name in the database.
My Play Framework "application.conf" is like this...
db.default.username="nameOfDatabaseUser"
db.default.password="passOfDatabaseUser"
db.default.driver=org.postgresql.Driver
db.default.url="jdbc:postgresql://urlofdatabase:5432/name_of_database"
Here's the thing. When my terminal user is named "nameOfDatabaseUser", it works. But when my terminal user has a different name, it connects to the database as the name of the current Linux terminal user.
In the above case it appears that Heroku tried to connect as a user lcnjgrwbmbffwv and there was no user lcnjgrwbmbffwv in the database.
How do I specify the default database username so that it doesn't use my terminal username?

Answer 1

The correct key to specify the user is db.default.user, not db.default.username.
