+The command validates the chain index entries for each epoch in the specified range, checking for missing or

 (which it is by default), it will attempt to backfill any missing entries using the 'ChainValidateIndex' API.
 
 Parameters:
   - '--from' (required): The starting epoch (inclusive) for the validation range. Must be greater than 0.
-  - '--to' (required): The ending epoch (inclusive) for the validation range. Must be greater than 0 and less

   - '--log-good' (optional, default: false): Whether to log details for tipsets that have no detected problems.
 
 Error conditions:
