TempoOutOfBounds
Check the argument values against the operation schema
The subnet owner gave sudo_set_tempo a tempo outside the allowed MIN_TEMPO to MAX_TEMPO range (360-50,400 blocks). Check the tempo argument against those chain constants and pick a value inside the bounds; only root may set a tempo outside them.
Declared by the SubtensorModule pallet; it classifies to the semantic code invalid_argument.
Remediation
Check the argument values against the operation schema
The same explanation is available in the terminal: btcli explain TempoOutOfBounds.
