The policy validator tool is not working with NFTs minted with plutus scripts

[AngelCastilloB]

I am minting the NFTs of my project using the following Plutus minting policy script:

{-# INLINABLE mkNFTPolicy #-}
mkNFTPolicy :: TokenName -> TxOutRef -> BuiltinData -> ScriptContext -> Bool
mkNFTPolicy tn utxo _ ctx = traceIfFalse "UTxO not consumed"   hasUTxO           &&
                            traceIfFalse "wrong amount minted" checkMintedAmount
  where
    info :: TxInfo
    info = scriptContextTxInfo ctx

    hasUTxO :: Bool
    hasUTxO = any (\i -> txInInfoOutRef i == utxo) $ txInfoInputs info

    checkMintedAmount :: Bool
    checkMintedAmount = case flattenValue (txInfoMint info) of
        [(_, tn', amt)] -> tn' == tn && amt == 1
        _               -> False

For example, the output script for the following NFT:

https://pool.pm/b431bb2eb71bbf88c86da85e9eafa609cc62dd9efda2562f345f31ee.Horrocube00000

is as follows:

Running the following command:

cardano-cli transaction policyid --script-file script.plutus

Where script.plutus is a file with the previous policy script as content returns:

b431bb2eb71bbf88c86da85e9eafa609cc62dd9efda2562f345f31ee

Which matches the policy id listed on the website:

https://pool.pm/policy/b431bb2eb71bbf88c86da85e9eafa609cc62dd9efda2562f345f31ee

However, if I try to place the script in the text box when the website immediately rejects it as "invalid policy".

Policies with PlutusScriptV1 scripts are not supported yet indeed.

Thank you for reporting.
