Bug

The application panicked (crashed).
Message: no entry found for key

This is a bug. We may have already fixed this in newer versions of Nargo so try searching for similar issues at https://github.com/noir-lang/noir/issues/.

@noir-lang/developerrelations looks like Nithin is running into issues with aztec docs.

@Nithin-Varma Can you provide the code you're trying to compile and the version of nargo you're compiling with?

[Nithin-Varma]

@TomAFrench

use aztec::macros::{functions::{initializer, private}, storage::storage};
use aztec::prelude::{AztecAddress, Map};
use easy_private_state::EasyPrivateUint;
use value_note::{balance_utils, value_note::ValueNote};

#[storage]
struct Storage {
counters: Map<AztecAddress, EasyPrivateUint, Context>,
}

#[initializer]
#[private]
fn initialize(headstart: u64, owner: AztecAddress) {
let counters = storage.counters;
counters.at(owner).add(headstart, owner, context.msg_sender());
}

#[private]
fn increment(owner: AztecAddress, sender: AztecAddress) {
unsafe {
dep::aztec::oracle::debug_log::debug_log_format(
"Incrementing counter for owner {0}",
[owner.to_field()],
);
}
let counters = storage.counters;
counters.at(owner).add(1, owner, sender);
}

unconstrained fn get_counter(owner: AztecAddress) -> pub Field {
let counters = storage.counters;
balance_utils::get_balance(counters.at(owner).set)
}

at this point i am just following docs to understand compiler and outputs better
nargo - 1.0.0
aztec - 0.67.0

i tried with 0.69.1 as well but seems like there are few issues with 0.69.1 while starting sandbox, so i downgraded to the 0.67.0

The documentation is linked to a specific version, so if you are trying compile a contract from the current docs with an older version of aztec-nargo, it wont work, you need to use the corresponding version source code. You can find the counter contract source for version 0.67.0 here: https://github.com/AztecProtocol/aztec-packages/blob/barretenberg-v0.67.0/noir-projects/noir-contracts/contracts/counter_contract/src/main.nr

You can find the code snippets for the corresponding sections wrapping in comments like // docs:start:storage_struct.

I just tried it with the counter contract source at version tag 0.67.0 and it compiles.

please mention this in the documentation, so that people who new to it wont get confused.
also, there is an error while running the sandbox with 0.69.1 version, to run sandbox i have downgraded to 0.67.0.
thank you for your response, will try with above code.
