FATAL ERROR: v8::FromJust Maybe value is Nothing #43304
Comments
Possibly already fixed in #42874. |
Do you know @airtable-keyhanvakil where this landed i.e. which version was it applied to and whether it covers Node.js 14.x? |
@ashishchandr70 It looks to be in v18.2.0. I asked about how to get it backported to earlier branches in that PR. |
I had this issue with vitest, I just updated it to the latest version |
Similar issue yet again in This happened after hitting

It would be useful if someone could provide a simple way to reproduce the crash. |
This is to workaround for the "FATAL ERROR: v8::FromJust Maybe value is Nothing." errors we see for our Windows and macOS test executions on Azure. The error is sporadic, but most consistently appears on Windows 2022 (Azure image '20230630.1.0' and Node v18.16.1. avajs/ava#2947 seems to suggest this is a Node.js issue as reported at nodejs/node#43304 Disabling the use of our own worker threads in minifier.js resolve the issue. Disabling worker threads in AVA resolves it too. Since we want to test our worker threads, we opted for the latter by setting the AVA option '--no-worker-threads' for all scripts executed in Azure. All this indicates an issue with using worker threads (or the workerpool package) from within workers.

Here's a small reproducible code sample. This crashes with the error 1/5 times for me. If I keep running this over and over I consistently get the crash. import { createApplication, Request } from '@nbit/bun';
import { expect, test } from 'vitest';
const home = () => ({ hello: 'world' });
const { defineRoutes, createRequestHandler } = createApplication();
const routes = defineRoutes(app => [
app.get('/', home),
]);
const requestHandler = createRequestHandler(routes);
test('should return the home page', async () => {
const request = new Request('http://localhost/');
const response = await requestHandler(request);
expect(response.status).toBe(200);
});

@ImLunaHey can you try with the latest v18.x? v18.3.0 is pretty old by now. A test case without third-party dependencies would help too. |
I believe |

I join the problem with 20.15.1 |
