trying to claim back the first player bet after deadline in the ZeroOneGame from ppbl gimbalabs course on pre-production_testnet I get an error when trying to build the claim transaction.

I have this Player 1 address addr_test1vpn9qvm8tuth36pm0ul70tn7hwl0rtjk6cw9k6gzw5g6pxc8cexwu

cardano-cli query utxo --address $(cat P1.addr) --testnet-magic 1
                           TxHash                                 TxIx        Amount

And this contract address addr_test1wrxhzl9vvcf2p8njp2metcf9mkapc9d2fj8a5fszv4ngnecge54yd which received the bet and NFTstate already.

cardano-cli query utxo --address $(cat contract1stGame.addr) --testnet-magic 1
                           TxHash                                 TxIx        Amount

f8f17e3515372fa9428abf3e0a30aedc3f11a6ef598d5f9838d35e2e45519bf3     1        5000000 lovelace + 1 665c8f0cdf7dc8b939d484d85f80d24c4c50af560be49c58d2b51f38.7a65726f4f6e6547616d65546573743031 + TxOutDatumHash ScriptDataInBabbageEra "f47634d3b1c1caccb51ab10c74958ccb464b0893c3e612b649a4484a6e50eeca"

Then I try to build the transaction to ClaimByFirstPlayer

cardano-cli transaction build --babbage-era \
--tx-in f8f17e3515372fa9428abf3e0a30aedc3f11a6ef598d5f9838d35e2e45519bf3#0 \

--tx-out $(cat P1.addr)+5000000+"1 665c8f0cdf7dc8b939d484d85f80d24c4c50af560be49c58d2b51f38.7a65726f4f6e6547616d65546573743031" \
--change-address $(cat P1.addr) \
--protocol-params-file parameters.json \
--invalid-before 17168436 \
--testnet-magic 1 \
--out-file tx.raw

But I receive the following error:

Command failed: transaction build  Error: The following scripts have execution failures:
the script for transaction input 0 (in the order of the TxIds) failed with: 
transaction input 0 (in the order of the TxIds) points to a script hash that is not known.

Is difficult to understand what it is going wrong from this error, I told that the --tx-in order may have been wrong, but after trying to make it better the error persists.

Is there any obvious mistake I am going through from the information given?

Mystery solved, what Plutus is trying to tell me is that I forgot to put the UTxO/--tx-in of the contract itself.

to the previous transaction I had to add the line

--tx-in f8f17e3515372fa9428abf3e0a30aedc3f11a6ef598d5f9838d35e2e45519bf3#1 \

That error is a weird way to say that the script couldn't find any UTxO related to the contract in the transaction being built.
