I'm working on a project using Vapor 4 in Xcode.

However, when I try to run a simple initial migration, an error occurs:

[ WARNING ] PSQLError(code: server, serverInfo: [sqlState: 28000, file: miscinit.c, line: 798, message: role "vapor_username" does not exist, routine: InitializeSessionUserId, localizedSeverity: FATAL, severity: FATAL]) (App/entrypoint.swift:24) [ DEBUG ] Application shutting down (Vapor/Application.swift:306) Swift/ErrorType.swift:200: Fatal error: Error raised at top level: PSQLError(code: server, serverInfo: [sqlState: 28000, file: miscinit.c, line: 798, message: role "vapor_username" does not exist, routine: InitializeSessionUserId, localizedSeverity: FATAL, severity: FATAL])

So the message says:

"role "vapor_username" does not exist"

• I have already started the server with the database using Docker, and it is running normally.

• docker-compose up db worked and the database was successfully launched.

What could be the problem?
