Adolf is a fork/vendored clone of github.com/openclaw/openclaw (v2026.6.11), free to diverge. Tree copied sans upstream .git; upstream remote added for future syncs. Node pinned to 24 (.nvmrc); engines already require >=22.19. Preserves docs/ARCHITECTURE.md.

| Historical Node + tsx "__name is not a function" crash and its cause |

Node + tsx crash |
Node + tsx "__name is not a function" crash
Status
Resolved. This crash does not reproduce on the current tsx version pinned in
package.json (4.22.3) or on current Node releases. Kept here in case a
future tsx/esbuild upgrade reintroduces it.
Original symptom
Running OpenClaw dev scripts through tsx failed at startup with:
[openclaw] Failed to start CLI: TypeError: __name is not a function
at createSubsystemLogger (src/logging/subsystem.ts)
at <caller> (src/agents/auth-profiles/constants.ts)
Line numbers are omitted; both files have changed since the original crash and the specific lines no longer match.
This appeared after dev scripts switched from Bun to tsx (2871657e,
2026-01-06) to make Bun optional. The equivalent Bun-based path did not crash.
It was originally observed on Node v25.3.0 on macOS; other platforms that run
Node 25 were considered likely to be affected too.
Cause
tsx transforms TS/ESM through esbuild with keepNames: true hardcoded in
its transform options. That setting makes esbuild wrap named function/class
declarations in a call to a __name helper so fn.name survives minification
and bundling. The crash means the helper was missing or shadowed at the call
site for that module in the affected tsx/Node combination, so __name(...)
threw instead of returning the wrapped value.
Current repro check
node --version
pnpm install
node --import tsx src/entry.ts status
Minimal isolated repro (loads only the module from the original stack trace):
node --import tsx scripts/repro/tsx-name-repro.ts
Both commands currently exit cleanly. If either throws __name is not a function again, capture the exact Node version, tsx version
(node_modules/tsx/package.json), and full stack trace before filing upstream.
Workarounds (if the crash returns)
-
Run dev scripts with Bun instead of
node --import tsx. -
Run
pnpm tsgofor type checking, then run the built output instead of the source throughtsx:pnpm tsgo node openclaw.mjs status -
Try a different
tsxversion (pnpm add -D tsx@<version>is a dependency change and needs approval per repo policy) to bisect whether the esbuild version it bundles reintroduced the bug. -
Test on a different Node major/minor to see whether the failure is version specific.
