Deployment via Orbit CLI didn't include argument even it show argument check sum

Hi devs,

When I using Orbit CLI via my CI/CD pipeline, I got issue that the argument is show in orbit but when it deployed the argument is not set

the argument I use

(record { log_settings=opt record { enable_console=opt true; in_memory_records=opt 10000; log_filter=opt "global,cashier=debug,token_storage=debug"; }; owner=principal "useor-pyaaa-aaaad-ac2ya-cai"; tokens = opt vec { record { details = variant { IC = record { ledger_id = principal "ryjl3-tyaaa-aaaaa-aaaba-cai"; index_id = opt principal "qhbym-qaaaa-aaaaa-aaafq-cai"; fee = 10000 : nat; }}; symbol = "ICP"; name = "Internet Computer"; decimals = 8; enabled_by_default = true; }; record { details = variant { IC = record { ledger_id = principal "mxzaz-hqaaa-aaaar-qaada-cai"; index_id = opt principal "n5wcd-faaaa-aaaar-qaaea-cai"; fee = 10 : nat; }}; symbol = "ckBTC"; name = "Chain Key Bitcoin"; decimals = 8; enabled_by_default = true; }; record { details = variant { IC = record { ledger_id = principal "ss2fx-dyaaa-aaaar-qacoq-cai"; index_id = opt principal "s3zol-vqaaa-aaaar-qacpa-cai"; fee = 2_000_000_000_000 : nat; }}; symbol = "ckETH"; name = "Chain Key Ethereum"; decimals = 18; enabled_by_default = true; }; record { details = variant { IC = record { ledger_id = principal "xevnm-gaaaa-aaaar-qafnq-cai"; index_id = opt principal "xrs4b-hiaaa-aaaar-qafoa-cai"; fee = 10_000 : nat; }}; symbol = "ckUSDC"; name = "Chain Key USD Coin"; decimals = 6; enabled_by_default = true; }; };})

After reinstall, it seems the list of token is not included

Following this [post](https://forum.dfinity.org/t/deployment-via-orbit-cli-didnt…-include-argument-even-it-show-argument-check-sum/62556) I found that there method `parse_arguments` used for canister install in tools/dfx-orbit/src/canister/util.rs silently convert `opt int` to None Here is the unit test I test the code ```rs #[cfg(test)] mod tests { use candid::Principal; /// Proves dfx-orbit untyped Candid encoding bug: tokens silently become None. /// /// Root cause chain: /// 1. `parse_idl_args().to_bytes()` encodes `decimals = 8` as `int` (no type info) /// 2. Canister expects `nat8` for decimals field /// 3. Candid int→nat8 coercion fails (Subtyping error) /// 4. Candid opt upgradeability rule: inner decode failure → silently becomes None /// 5.
