PR #77963: fix(net): sanitize HeadersInit to prevent Symbol-keyed header crashes on Node 22

• Repository: openclaw/openclaw
• Author: VintageAyu
• State: open | merged: False
• Link: https://github.com/openclaw/openclaw/pull/77963

Description (problem / solution / changelog)

Summary

Describe the problem and fix in 2–5 bullets:

• Problem: Node.js 22's native undici engine throws a TypeError when a HeadersInit object contains Symbol keys (e.g., Symbol(sensitiveHeaders)).
• Why it matters: This prevents standard libraries like discord.js from initializing or making network requests within OpenClaw plugins, as OpenClaw's global fetch interceptors inadvertently pass these Symbols to the native Headers constructor.
• What changed: Introduced a sanitizeHeadersInit utility to strip non-string keys before they reach new Headers() or native fetch() calls.
• What did NOT change (scope boundary): The core network dispatching logic and existing header values remain untouched; only the initialization object keys are normalized.

Real behavior proof

• Behavior or issue addressed: Fixed "ByteString" conversion error on Node 22 when using fetch-heavy plugins.
• Real environment tested: WSL2 (Ubuntu) running Node.js v22.1.0.
• Exact steps or command run after this patch: Executed a standalone script that passes a Symbol-keyed record to the patched Headers initialization flow.
• Evidence after fix:

ayu@MSI:~/openclaw-main$ npx tsx scratch/ultimate_proof.ts
💎 STARTING ULTIMATE BEHAVIOR PROOF...
Testing against a REAL library (discord.js v14) through OpenClaw core.

Attempting discord.js client.login()...
(This normally crashes OpenClaw on Node 22 due to Symbol(sensitiveHeaders))

✅ ULTIMATE PROOF SUCCESS!
   The request successfully passed through OpenClaw's Headers constructor.
   Received standard Discord error: 'An invalid token was provided.'

-> Observed result after fix: Native Headers constructor accepts the sanitized object and correctly retrieves string-keyed headers. -> What was not tested: Performance impact on extremely high-frequency fetch calls (though overhead is minimal).

ROOT CAUSE

-> Root cause: Node.js 22's undici implementation strictly validates HeadersInit keys. OpenClaw's proxy-capture and runtime-fetch layers were passing objects containing internal tracking Symbols to this constructor. -> Missing detection / guardrail: Lack of normalization at the boundary between OpenClaw's interceptors and the native fetch runtime.

BEHAVIOR CHANGE

Before:
[Plugin Fetch] -> [OpenClaw Interceptor (Adds Symbol)] -> [Native Headers(init)] -> ❌ CRASH

After:
[Plugin Fetch] -> [OpenClaw Interceptor] -> [sanitizeHeadersInit()] -> [Native Headers(init)] -> ✅ SUCCESS

Environment

• OS: WSL2 (Ubuntu)
• Runtime/container: Node.js v22.1.0
• Model/provider: google
• Integration/channel (if any): discord.js v14

PR #78058: fix: strip symbol keys from fetch headers

• Repository: openclaw/openclaw
• Author: bryce-d-greybeard
• State: open | merged: False
• Link: https://github.com/openclaw/openclaw/pull/78058

Description (problem / solution / changelog)

Summary

Fixes the fetch wrapper boundary so plain header dictionaries carrying enumerable symbol metadata are cloned with only string-keyed headers before being forwarded to native fetch/undici. This prevents Node 22's Headers constructor from crashing on symbol keys such as Symbol(sensitiveHeaders) while avoiding mutation of caller-owned header objects.

Changes

• Sanitizes only plain-object init.headers values with enumerable symbol keys in wrapFetchWithAbortSignal.
• Preserves Headers, tuple-array headers, and plain header objects without symbol keys unchanged.
• Adds regression coverage for symbol-keyed header dictionaries and the pass-through case.

Testing

• PATH="/tmp/openclaw-pnpm-shim:$PATH" pnpm vitest run src/infra/fetch.test.ts — passed, 18 tests.
• git diff --check — passed.
• PATH="/tmp/openclaw-pnpm-shim:$PATH" node scripts/check-changed.mjs — ran all gates through pairing account guard, then process was SIGKILLed at exit/final step; standalone PATH="/tmp/openclaw-pnpm-shim:$PATH" node scripts/check-pairing-account-scope.mjs passed immediately.

Fixes #77846
