nitro v3 crash on tanstack start when building caused by puppeteer

[nick22985]

Hey,
Could someone help me figure out a way I can debug what is causing this crash when I build. When using v2 nitro it builds fine when i switch to the beta v3 version it causes this crash when i run vite build (the preset seemingly doesnt matter i tried node-server and bun both had the same crash). This is only happening in one of my projects and builds fine on others. I want to figure out how to make a way to minimally reproduce this but I dont know where to really start on ways to figure out why this project causes this to make a bug report / issue

Can you please share a reproduction? 🙏🏼

Hey, would love to provide something however the project that it is happening on is not open source. I am happy to give you and other maintainers access to the repo if it helps. But I do understand if not. I am happy trying to attempt to get to the bottom of it. Just not sure what direction to go to get started with what is causing it.

@pi0 I have successfully figure out what is causing this the repo is here: https://github.com/nick22985/tanstackstart-nitrov3-crash

Specifically what is causing it is puppeteer
serverFn is called from the frontend here: https://github.com/nick22985/tanstackstart-nitrov3-crash/blob/d0399cbb5ae4f17bedafb188bd358dba9a8a60e3/src/routes/index.tsx#L7-L7

serverfn that initializes the puperteer instance:
https://github.com/nick22985/tanstackstart-nitrov3-crash/blob/d0399cbb5ae4f17bedafb188bd358dba9a8a60e3/src/lib/server/serverFn/test.ts#L4-L19

what causes it:
https://github.com/nick22985/tanstackstart-nitrov3-crash/blob/d0399cbb5ae4f17bedafb188bd358dba9a8a60e3/src/lib/server/screenshot-service.ts#L5-L30

assume it something with the size of puppeteer and having to compile it
.nitro/vite/services/ssr/assets/screenshot-service-BytB4e8u.js 12,830.31 kB

if you go to vite.config.ts i have put in the v2 nitro config also so you can see it build in v2 sucessfully the file size is much smaller in v2
├─ .output/server/chunks//screenshot-service-BCTYhzM1.mjs (952 B) (444 B gzip)
├─ .output/server/chunks//screenshot-service-BCTYhzM1.mjs.map (633 B) (277 B gzip)

Hey @pi0,
Do you want me to create a issue for this or is this tracked in a issue?

Regards,
Nick
