@sefi18 Hi again,
I was able to successfully create a supergraph using the @extends directive. There is a problem that the directive is not removed at the end (which will need to be addressed but is possibly benign). However, I am unable to replicate your error.
At this point, it would be extremely helpful if you could share your subgraphs with me. Or at least just all and any root operations (subscription, query, mutation), also making sure ALL of those feature @extends.
Thanks,
David
