Error message

adapter rejected input: invalid_cwd

What it means

rawAdapter.normalizeInput throws AdapterRejectedInput('invalid_cwd') when r.cwd (or the process.cwd() fallback) is not a non-empty string. This adapter is the escape hatch for arbitrary payloads, so the only hard requirement it enforces is a usable cwd plus defaults sessionId to 'unknown'.

Solutions

  1. Pass cwd as a valid absolute directory string in the raw payload
  2. Omit cwd to use process.cwd()
  3. Fix the upstream producer so it emits cwd as a string, not a number/object
  4. Catch AdapterRejectedInput, check .reason === 'invalid_cwd', and sanitize the payload before retry

Example fix

// before
rawAdapter.normalizeInput({ cwd: '' });
// after
rawAdapter.normalizeInput({ cwd: process.cwd() });
Defensive patterns

Strategy: validation

Validate before calling

if (!raw || typeof raw.cwd !== 'string' || raw.cwd.length === 0) raw = { ...(raw ?? {}), cwd: process.cwd() };

Type guard

function hasValidCwd(v: unknown): v is string { return typeof v === 'string' && v.length > 0; }

Try / catch

try { adapter.normalizeInput(raw); } catch (e) { if (e instanceof AdapterRejectedInput && e.reason === 'invalid_cwd') { /* normalize payload and retry */ } else throw e; }

Prevention

When it happens

Trigger: Calling the raw adapter with raw where cwd is '', null, a number, or another non-string, and process.cwd() fallback also unavailable; or running from a deleted working directory.

Common situations: Generic integrations forwarding third-party JSON where the cwd field has the wrong type; scripts run via exec from an unlinked directory; test fixtures with malformed cwd.

Understand the failure class

Background: "Must be a positive integer", "Invalid value", "Unsupported": the invalid-argument-value error family, when a library rejects the value you pass — this error's family across 35 libraries.
