Can't register my stake pool on Cardano (StakeDelegationImpossibleDELEG)

Question

I'm following the official process here on the Cardano tutorial.

Firstly, I have to show you I already have the fund here:

// cardano-cli query utxo --address $(cat payment.addr) --mainnet

                           TxHash                                 TxIx        Amount
--------------------------------------------------------------------------------------
4c782ea34b517b99e508f675ea1019bc6c60738570ae7dbf074d3ad2d44e8eef     0        600000000 lovelace + TxOutDatumNone
75e262eb49ba1237b1ee00a4854935d67bd05988baed5472a7ff97b49551d386     0        17648934 lovelace + TxOutDatumNone
e663b2e14f180ae341a49bcbde247d074d944942cc3b8794277645ac1e49d377     0        8336205 lovelace + TxOutDatumNone

In the process, I've already created my pool-registration.cert file.

We can double-check thanks to this:

// cat pool-registration.cert
{
    "type": "CertificateShelley",
    "description": "Stake Pool Registration Certificate",
    "cborHex": "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"
}

// cat delegation.cert 
{
    "type": "CertificateShelley",
    "description": "Stake Address Delegation Certificate",
    "cborHex": "83028200581c084cf0adf9fe75b3e479e6c837676bb85016ae891c624cf59004a009581ce9c55b1910e7fdcacf2db1be6f20fadff0e5d68d6566b223698031ab"
}

Then after calculating my fees and taking a look at the hereafter, I'm building my transaction like this:

cardano-cli transaction build-raw \
    --tx-in 4c782ea34b517b99e508f675ea1019bc6c60738570ae7dbf074d3ad2d44e8eef#0 \
    --tx-out $(cat payment.addr)+99802951 \
    --invalid-hereafter 75915180 \
    --fee 197049 \
    --out-file tx.raw \
    --certificate-file pool-registration.cert \
    --certificate-file delegation.cert

Finally, I'm signing and sending my message like this:

cardano-cli transaction sign \
    --tx-body-file tx.raw \
    --signing-key-file payment.skey \
    --signing-key-file stake.skey \
    --signing-key-file cold.skey \
    --mainnet \
    --out-file tx.signed

cardano-cli transaction submit \
    --tx-file tx.signed \
    --mainnet

My result after this is:

Command failed: transaction submit  Error: Error while submitting tx: ShelleyTxValidationError ShelleyBasedEraBabbage (ApplyTxError [DelegsFailure (DelplFailure (DelegFailure (StakeDelegationImpossibleDELEG (KeyHashObj (KeyHash "084cf0adf9fe75b3e479e6c837676bb85016ae891c624cf59004a009")))))])

Thank you if somebody can help, I will add more information if needed.

You first need to create a registration certificate for the stake key, before being able to delegate it. You can submit all 3 certificates in the same transaction, just add the key registration certificate between the other 2 certificates. You can see all the steps in my documentation here: https://apexpool.gitbook.io/stake-pool-scripts/stake-pool-registration/stake-pool-scripts/stake-key-registration
