Type PaymentPubKeyHash not found

Question

I have the following datum type

data ProjectSubmitDatum = ProjectSubmitDatum
  { vProjectOwner :: PaymentPubKeyHash,
    vProjectRegistrationFee :: Integer,
    vProjectCategory :: BuiltinByteString,
    vFundPayIdentifier :: PaymentPubKeyHash
  }
  deriving (Show)

I also have the module imported like this

import Ledger.Address 

The following error pops up when i run cabal repl

src/QuadraticVFSC.hs:45:19: error:
    Not in scope: type constructor or class ‘PaymentPubKeyHash’
   |
45 |   { vFundOwner :: PaymentPubKeyHash,
   |                   ^^^^^^^^^^^^^^^^^

Answer 1

you need to import either the whole module like this:

import Ledger

or the specific type like this:

import Ledger (PaymentPubKeyHash)

Answer 2

You neeed to import PaymentPubKeyHash it like the following:

import Ledger.Address qualified as Address (Address, PaymentPubKeyHash(..))

This works for me and you can checkout my working code on testnet here:
