I'm regularly getting some of these errors when calling the check endpoint:

Could not check permissions from the SpiceDB service. Error: 2 UNKNOWN: error dispatching request: unable to read namespace config: context canceled

  code: 2,
  details: 'error dispatching request: unable to read namespace config: context canceled',
  metadata: Metadata {
    internalRepr: Map(2) {
      'io.spicedb.respmeta.dispatchedoperationscount' => [Array],
      'io.spicedb.respmeta.cachedoperationscount' => [Array]
    },
    options: {}
  }
}

That seems like an internal error, either it's a bug or it should surface a more readable error for the developer? "namespace config" and "context canceled" aren't concepts I've encountered in the docs
