@secure-exec/v8 crashes on Lambda startup

[bjorntechTobbe]

Using secure-exec with @secure-exec/v8 in AWS Lambda, the V8 runtime crashes during startup before sending the socket path back to the parent process.

Environment

• AWS Lambda
• Node.js 20
• secure-exec@0.2.0-rc.2
• @secure-exec/v8@0.2.0-rc.2

Context
This does not appear to be a packaging issue. The deployed artifact contains the expected packages, including the Linux native package.

Observed errors
Error: V8 runtime process closed stdout before sending socket path
at Interface. (file:///var/task/node_modules/@secure-exec/v8/dist/runtime.js:458:24)
Then:
ReferenceError: Cannot access 'sessionHandlers' before initialization
at rejectPendingSessions (file:///var/task/node_modules/@secure-exec/v8/dist/runtime.js:183:26)
at ChildProcess. (file:///var/task/node_modules/@secure-exec/v8/dist/runtime.js:99:9)

Minimal usage
const { NodeRuntime, createNodeDriver, createNodeRuntimeDriverFactory } =
await import("secure-exec");
const runtime = new NodeRuntime({
systemDriver: createNodeDriver({
permissions: {
fs: () => ({ allow: false }),
network: () => ({ allow: true }),
},
}),
runtimeDriverFactory: createNodeRuntimeDriverFactory(),
memoryLimit: 64,
cpuTimeLimitMs: 10_000,
});
const runResult = await runtime.run(wrappedCode);

Expected

• the V8 runtime starts successfully
• if startup fails, cleanup should not throw a secondary ReferenceError
