Hello everyone! We have been experimenting with self-serve Keto, Keto API and grpc library. We managed to work with the write and read APIs by using pre-defined namespaces in config. But when we migrated to Ory Permission Language by defining relations and Namespaces by ts types we faced errors - the created Namespaces were not found when using:

import * as grpc from '@grpc/grpc-js';
import keto from '@ory/keto-grpc-client';

// Making user_id to have viewer relation to org_id organization.

const writeClient = new keto.writeService.WriteServiceClient(
  '127.0.0.1:4467',
  grpc.credentials.createInsecure()
);

const relationTuple = new keto.relationTuples.RelationTuple();
relationTuple.setNamespace('Organization');
relationTuple.setObject('org_id');
relationTuple.setRelation('viewer');

const subject = new keto.relationTuples.Subject();
subject.setId('user_id');

relationTuple.setSubject(subject);

const tupleDelta = new keto.write.RelationTupleDelta();
tupleDelta.setAction(keto.write.RelationTupleDelta.Action.ACTION_INSERT);
tupleDelta.setRelationTuple(relationTuple);

const writeRequest = new keto.write.TransactRelationTuplesRequest();
writeRequest.addRelationTupleDeltas(tupleDelta);

writeClient.transactRelationTuples(writeRequest, (error) => {
  if (error) {
    console.log('Encountered error', error);
  } else {
    console.log('Successfully created tuple');
  }
});

I am wondering if there are any examples on how this should work? Do we need to pre-register Orgs and Users with Tuples and cli command? Cannot understand why it keep saying that it cannot find Organization namespace. Any suggestions or advice?

you have to make sure it is written the same way in the new config as in the old config
