I think this is the same issue as this other topic, let’s keep all the discussion there:
> [@PG Error on rebuild - column "token" of relation "email\_tokens" does not exist](https://meta.discourse.org/t/pg-error-on-rebuild-failed-migration/211934/6):
>
> Please can someone with this issue try running this on the rails console, and share your result: ./launcher enter app rails c … DB.query "SELECT table\_schema, table\_name, column\_name FROM INFORMATION\_SCHEMA.COLUMNS WHERE table\_name='email\_tokens' AND column\_name='token';"
