InvalidModality
Error Removed v101 → v127, v133 → v150 (removed) 7.2Input validation failed or the signing account lacks permission.
What This Means
Input validation failed or the signing account lacks permission.
Common Causes
- Signing with the wrong key (e.g., hotkey instead of coldkey)
- Parameter value outside acceptable range
- Operation requires sudo or specific owner account
How to Fix
- Check which key should sign: most staking ops need coldkey, weight ops need hotkey
- Verify parameter ranges match the expected constraints
- For owner-only calls, confirm you own the target resource
