Direct Transfer raises JS error on page load
Problem
When using DT to migrate groups and projects one needs to connect to a target instance to list all the available groups to import. The page the lists the available groups to import raises the following JS error on load:
The error is being raised in https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/assets/javascripts/import_entities/import_groups/components/import_table.vue#L521 and it seems that there are no namespaces available to set the default target namespace.
