I’m trying to deploy the ledger for use with my local dfx. I’ve pulled a few things together and think I’m doing things correctly, but am hitting a wall.

dfx version: 0.7.1
os: macOS 11.3

dfx.json
{
  "canisters": {
    "ledger": {
      "build": "cargo build --target wasm32-unknown-unknown --package ledger-canister --release",
      "candid": "./candid/ledger.did",
      "wasm": "../rs/target/wasm32-unknown-unknown/release/ledger-canister.wasm",
      "type": "custom"
    }
  },
  "defaults": {
    "build": {
      "packtool": ""
    }
  },
  "dfx": "0.7.1",
  "networks": {
    "local": {
      "bind": "127.0.0.1:8000",
      "type": "ephemeral"
    }
  },
  "version": 1
}

canister_ids.json - I manually added this and put rrkah-fqaaa-aaaaa-aaaaq-cai as the ledger principal because I wanted it to match production ID/Principals.

{
  "__Candid_UI": {
    "local": "ryjl3-tyaaa-aaaaa-aaaba-cai"
  },
  "ledger": {
    "local": "rrkah-fqaaa-aaaaa-aaaaq-cai"
  }
}

Deploy Command - minting_account is the Account ID for index 0 of the cycles_minting_canister on ic0…maybe this isn’t what this is supposed to be but I don’t think it matters for deployment. The other vec is the account ID from my dfx ledger account-id

dfx deploy ledger --argument 'record {minting_account="b07xxxxxxx93"; initial_values=vec {record{"e2xxxxxxxxx87e";record{e8s=1000000000;}}}; max_message_size_bytes=null;transaction_window=null;archive_options=null;send_whitelist=vec{};}'

The output I receive is below:

Previously I’ve also received:

Any thoughts on what I’m doing wrong here? I’ve basically set dfx up in the rs directory of github.com/dfinity/ic. Maybe there is something in this config that messes with something? It seemed like a good start to do what I’m trying to do.

In case it is important, here is the output from dfx start:

I’ll add that a motoko canister is installing just fine. Perhaps this is internal and one of the system canisters needs to exist first? I’m going to poke around in the code.

The replica returned an HTTP Error: Http Error: status 500 Internal Server Error, content type "text/plain; charset=utf-8", content: Broken pipe (os error 32)

This error occurs because the Wasm module you’re trying to install is too large. Previously the http handler would return a better error message from the replica (one about ingress message size exceeding the limit.)
It’s not present in dfinity/ic but the ledger and other nns canisters are optimized. You can find a similar optimization script in the cycles wallet here: cycles-wallet/build.sh at main · dfinity/cycles-wallet · GitHub

I’m not sure about this one however; how consistently do you see this?
