In our api schema generation code, we iterate through a sorted list of endpoints[0]. We build a list of resource examples as we go. We store them by a 'resource_path' (eg /pulp/api/v3/repositories/file/file/{repository_pk}/')[1] but look them up 'resource_other_path' (eg /pulp/api/v3/repositories/file/file/{pulp_id}/')[2].

Consider the following sorted set of endpoints:

'/pulp/api/v3/repositories/file/file/{pulp_id}/'
'/pulp/api/v3/repositories/file/file/{repository_pk}/versions/'
'/pulp/api/v3/repositories/file/file/{repository_pk}/versions/{number}/'

When we get to the second endpoint, the resource_other_path is '/pulp/api/v3/repositories/file/file/{pulp_id}/' which exists in our resource_example because it was added when we processed '/pulp/api/v3/repositories/file/file/{pulp_id}/'.

But now consider a second set of endpoints:

'/pulp/api/v3/exporters/file/filesystem/{exporter_pk}/exports/',
'/pulp/api/v3/exporters/file/filesystem/{exporter_pk}/exports/{pulp_id}/',
'/pulp/api/v3/exporters/file/filesystem/{pulp_id}/',

When it goes to process the first item, it will try to lookup '/pulp/api/v3/exporters/file/filesystem/{pulp_id}/' which doesn't yet exist.
