Faucet return address

Hi, I am trying to return my faucet in testnet but when submitted transaction, it gives “option --address: Failed reading: invalid address” error.
I was able to send ADA to other address.

Looking into the return address (written in https://testnets.cardano.org/en/cardano/tools/faucet/),
I searched it on blockchain explorer (https://cardano-explorer.cardano-testnet.iohkdev.io/en).
It looks to me that this address does not exist.

Could anyone tell where to see the correct address so I can return ADA?(not your wallet address!)
Thank you,

I filed a bugreport about that.
I ended up sending the money to where I received it from.

Thank you! I will watch.
