Error deploying the ledger locally: "No more values on the wire"

I try to deploy the ledger locally as displayed in the documentation (https://internetcomputer.org/docs/current/developer-docs/integrations/ledger/ledger-local-setup) but get an issue "Deserialization Failed: “No more values on the wire, the expected type record”. Any idea?

The doc as script:

#!/usr/bin/env bash

# Install ledger locally as documented in:
# https://internetcomputer.org/docs/current/developer-docs/integrations/ledger/ledger-local-setup

Found it. The issue is that you have to configure dfx.json twice as displayed in the documentation.

  1. First with a private did
{
  "canisters": {
    "ledger": {
      "type": "custom",
      "wasm": "ledger.wasm",
      "candid": "ledger.private.did"
    }
  }
}

  1. then install ledger

  2. then update again dfx.json

"ledger": {
  "type": "custom",
  "candid": "ledger.public.did",
  "wasm": "ledger.wasm",
  "remote": {
    "candid": "ledger.public.did",
    "id": {
      "ic": "ryjl3-tyaaa-aaaaa-aaaba-cai"
    }
  }
}
