btcli wallet faucet --wallet.name owner --subtensor.chain_endpoint ws://127.0.0.1:9944

get the error：
Decrypting...
❌ Failed: Subtensor returned InvalidDifficulty(Module) error. This means: The supplied PoW hash block does not meet the network difficulty. | Please consult https://docs.learnbittensor.org/errors/subtensor#invaliddifficulty.

how to solve this? three month ago, it was alright, but now, with the latest main version of subtensor, failed.

For anyone who comes across this issue, here is a workaround for running on a local chain:
navigate to pallets/subtensor/src/subnets/registration.rs，
change the difficulty to 1 in the do_faucet func, then rebuild, should work fine.

 pub fn do_faucet( ...) {
    ...
    // let difficulty: U256 = U256::from(1_000_000); // Base faucet difficulty.
    let difficulty: U256 = U256::from(1); // Base faucet difficulty.

   ...
}
