Can't use backlinks if a link with the same name is computed

• EdgeDB Version: 1.0b2+ga7130d5c7.cv202104290000
• OS Version: macOS Big Sur / MacBook Air (M1, 2020) / Memory: 8 GB

Steps to Reproduce:

Simplified Schema;

using extension graphql;

module default {
    type User {
        required property email -> str {
            constraint exclusive;
        }
        multi link entries := .<author[IS Entry]; 
    }

    type Entry {
        link author -> User; 
        link topic := .<entries[IS Topic];
    }

    type Topic {
        multi link entries -> Entry; 
    }
};

GraphQL Query;

User {
      email
      entries {
        topic {
          id
        }
      }
}

When trying to use this query I am getting “QueryError: relation "edgedbpub.718fcee6-e765-11eb-9572-8bb96a65cb68_t" does not exist” error

With the following schema change it’s working well. I think this is a name collision issue. I wonder if this is a bug or am I doing something wrong?

using extension graphql;

module default {
    type User {
        required property email -> str {
            constraint exclusive;
        }
        multi link entries := .<author[IS Entry]; 
    }

    type Entry {
        link author -> User; 
        link topic := .<topic_entries[IS Topic];
    }

    type Topic {
        multi link topic_entries -> Entry; 
    }
};

It looks like we do now produce a proper error when trying to create the schema: cannot follow backlink 'entries' because link 'entries' of object type 'default::User' is computed

@kafein yeah, this will either be fixed or made to produce an error (though I think probably fixed). It shouldn’t be blocking you though, since you can work around it with a name change?
