Whats the appropriate way to - via the gRPC client - validate if a transaction of relation tuples succeeded or failed?

wres, err := write.TransactRelationTuples(context.Background(),&ketoV1.TransactRelationTuplesRequest{
		RelationTupleDeltas: deltas,
	})

If I specify a non-existent namespace in the deltas,

err

is nill and I can't really get anything useful out of

wres

hm in case of deletion, there should be no error as the end state of what you requested is there (i.e. they are already deleted) in case of insertion that should give you an error, if it does not it is a bug

Makes sense. I'll just confirm that it was insertions indeed 😄

haha well, glad that it does work now
