Map CleverVault contract error codes to typed errors in the vault client - #116
Conversation
Add VaultErrorCode, a TypeScript mirror of the contract's VaultError enum, and VaultContractError, thrown by agent-vault-client.ts when a simulated, sent, or polled invocation reverts with a mapped or unmapped numeric contract error. Callers can branch on err.code/err.codeName; unknown codes are preserved with known: false rather than swallowed, and non-contract failures (network, auth, malformed tx) are never misclassified. The contract error code is recovered from diagnostic events (send/poll path) or from the HostError string (simulation path), since the transaction result XDR itself never carries the numeric code. vault-errors.test.ts parses contracts/agent-vault/src/lib.rs directly and fails if VaultErrorCode drifts from the Rust VaultError enum, enforced by the existing npm test CI job. Documented in docs/development.md.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Propagate typed contract errors from public vault methods.
signAndSubmit and createTask now create VaultContractError instances. The surrounding catches in createTask, releasePayment, and completeTask log only err.message and return null or void. Callers cannot branch on code, known, or inspect raw.
Re-throw VaultContractError, or return a discriminated failure result that preserves it. Keep the null fallback only for non-contract failures if that behavior is required.

Pull request overview
This PR introduces typed, branchable errors for CleverVault contract reverts in the orchestrator’s vault client by mirroring the contract’s VaultError enum in TypeScript and extracting numeric contract error codes from simulation/send/poll failure shapes.
Changes:
- Added
VaultErrorCode+VaultContractErrorand helpers to extract contract error codes from diagnostic events or simulation error strings. - Updated
agent-vault-client.tsto throwVaultContractErrorfor contract reverts across simulate/send/poll paths. - Added CI-enforced drift detection via a Vitest unit test parsing
contracts/agent-vault/src/lib.rs, and documented the sync mechanism.

CodeRabbit flagged that createTask/releasePayment/completeTask swallowed VaultContractError to null/void, so no caller could ever branch on err.code for the busiest call sites. Verified against actual callers: releasePayment's only caller (executor.ts) already treats a failed release as fatal to the step either way, so re-throwing there only sharpens the failure message, it doesn't change control flow. createTask and completeTask are left as swallow-to-null/void — their callers in server.ts rely on that for graceful degradation (createTask: continue without vault tracking; completeTask: an already-completed-task revert during finalization must not flip a successful task run to failed).
|
Re the CodeRabbit suggestion to re-throw `VaultContractError` from `createTask`, `releasePayment`, and `completeTask`: applied it to `releasePayment` only (a6a35e9). Checked each function's actual callers before deciding:
Left `createTask`/`completeTask` swallowing to `null`/`void` as before, they still log the mapped VaultError code/name via `err.message`, they just don't propagate the exception given the current callers' control-flow assumptions. |
Closes #89.
What changed
packages/orchestrator/src/vault-errors.ts:VaultErrorCode, a TypeScript mirror of the contract'sVaultErrorenum (contracts/agent-vault/src/lib.rs), andVaultContractError, a typed error carryingcode,codeName,known, and the original raw response.agent-vault-client.tsnow throwsVaultContractErrorat every point a simulated, sent, or polled invocation reverts with a numeric contract error, instead of a genericErrorwith an opaque message. Non-contract failures (network errors, auth failures, malformed transactions) still throw a plainErrorand are never misclassified as aVaultError.VaultContractError, withknown: falseand the raw numeric code preserved rather than swallowed.Extracting the numeric code
The transaction result XDR itself (
errorResult/resultXdr) never carries the specificVaultErrordiscriminant, only a generic "trapped" result code. The actual number is only available from:HostError: Error(Contract, #N)string inSimulateTransactionErrorResponse.error.scvError(sceContract(N))value inside a diagnostic event, when the RPC node returns diagnostics.extractContractErrorCodetries diagnostic events first, falling back to regex-parsing the simulation error string. Both paths are covered byagent-vault-client.ts's six throw sites (buildUnsignedXdr,signAndSubmit,pollForConfirmation,submitSignedXdr, andcreateTask's inline flow).Sync mechanism
Went with a unit test over codegen or a shared JSON manifest:
vault-errors.test.tsparsescontracts/agent-vault/src/lib.rsdirectly and asserts every variant name and discriminant matchesVaultErrorCodeexactly. This needs no new build step or workflow — it runs as part of the existingnpm testCI job, so a PR that adds or renumbers aVaultErrorvariant without updating the TS mirror fails CI immediately. Documented indocs/development.md.Test plan
npm test— all vault-errors.test.ts cases pass (14 tests): sync check against lib.rs, extraction from diagnostic events, extraction from simulation error strings, non-contract failures returnnull/plainError, unknown codes preserved withknown: false.cargo testincontracts/agent-vault— unaffected, all 127 tests pass (contract itself untouched).npm run lint/npm run format:checkon the changed files.Summary by CodeRabbit
