Error : RuntimeWarning: Got an error checking a consistent migration history performed for database connection ‘default’: could not translate host name “postgres.railway.internal” to address: No such host is known.

I’m evaluating the use of django for the migration of a SQLite database to Postgres.
The database was not created as a django project, but instead used for other applications.
I’m attempting to configure django to do routine migrations of various development SQLite databases to Postgres.
