NoNeuronIdAvailable
A chain-side capacity limit was hit; reduce the size or count of the request
Registration could not obtain a uid: the subnet's MaxAllowedUids is 0, or the subnet is full and every neuron is immune from pruning. Check SubnetworkN versus MaxAllowedUids for the netuid and retry after immunity periods expire.
Declared by the SubtensorModule pallet; it classifies to the semantic code limit_exceeded.
