Hi @Prashant4900

This appears to be a problem in migration files.

Can you include that initial migration from your accounts app? It must be causing the issue with filer

@marksweb Here is the migration file

@Prashant4900 ok, so filer's initial migration depends on the auth initial migration. So your accouts app wants filer to install first and filer wants your accounts app to install first.

To resolve, don't include the filer field on your model until after the first migration. So take the filer field out of the model, create the migration, then add the field back in and create another migration.
