SubNetworkDoesNotExist
Error Removed v290 → v315 (removed) 28.11The subnet does not exist.
From Chain Metadata
The subnet does not exist.
What This Means
The subnet does not exist.
Common Causes
- Typo in the netuid parameter (e.g., 12 vs 21)
- The subnet was dissolved or doesn't exist yet
- Using testnet netuids on mainnet or vice versa
How to Fix
- Query SubtensorModule.NetworksAdded(netuid) - returns true only for valid subnets
- Valid mainnet netuids are typically 0-52 (but verify current list)
- For subnet 0 (root network), you need minimum stake - check SubtensorModule.MinStakeForRoot
