Is

--explain

turned off on SpiceDB Serverless? When running

zed permission check <specific relationship> --explain

I get

Error: rpc error: code = Internal desc = stream terminated by RST_STREAM with error code: NO_ERROR

error back. If I load the data in playground from within the authzed dashboard the same query returns a tree with explanation.

It's not disabled, this is unfortunately a known bug we haven't spent enough time figuring out.

Is there a workaround?

none that I know of, unfortunately. Authzed Dedicated does not have this problem, and you run it against your own deployment of SpiceDB using the SpiceDB Operator
