How to debug generate process when showing error 404

[TeddyHuang-00]

nuxt generate with ssr: false works just fine, but when I set ssr: true and the prerender step will complain that some payload (I guess?) json files are missing. And since their names are sort of hash-ed (e.g. /api/_content/query/wxmlyJ2dlX.1692374233767.json), how can I debug the generate process to see who and where is making such queries so that I can fix things up?

It is not a huge problem as I've got ssr: false as a workaround, but giving up SSR seems to be a huge loss for a document driven site.

Yeah, never mind the original question on how to debug command, I found that this can be done quite easily with VS Code debug session. Now the problem is the the error is generated from

await nitro.hooks.callHook("prerender:routes", routes);

And I need to look for where the hook is registered and what it does....

I found that the problem lies in the header URLs under the name x-nitro-prerender. And three of my routes generated one faulty query JSON each, and all of them happened to be only include a div tag in the template. Still testing out solutions....

EDIT: BTW, this is generated at the line 98-103 in the subfunction generateRoute of function prerender in file nitropack@[ver]/node_modules/nitropack/dist/shared/nitro.[xxx].mjs.

Did you ever solve this? I'm having the same problem, interestingly with the same hash wxmlyJ2dlX.

Well I did solve the issue, but I have done that through many trials and errors, so that I cannot recall what steps are the solution to the problem. But I did remember upgrading to a newer version of Nuxt and it produces the exact error and I believe that is related to some pages being needed without definition in the pages directory. I strongly suggest you check your Nuxt version and upgrade if you can, and also see if you are referring to /subdir/ while using file structure like pages/subdir/[slug].vue without defining pages/subdir/index.vue. Hope this is helpful to you!
