Hi folks,

I tried to modify my pool pledge via cntools on mainnet and get the following error:

```auto
Invalid argument `transaction'

Usage: cardano-cli
                     ( address

                     )

```

I’ve tried a few things and searched but haven’t found any real clues as to what the problem could be. While I was trying things out, I also looked at the key files. In pool.cert it still says “type”: “CertificateShelley”. Could that be the problem? Do I have to upgrade the pool certificates from shelly to conway? I haven’t found anything about that either.

Additional information:  
I have two owner wallets. One of them is secured with a Ledger hardware wallet.

Could it have been that easy? The transaction went through without any errors!

Can you tell me what has changed with the new version so that it works now?

Many thanks!!!

Good question, i don’t know…  
CNTools 13.2.2 was not fully compatible with cnode 10.1.1 or 10.1.2.  
That was fixed with 13.3, but it’s not actual release.
