Bug reproduction: web fetch fails on https://gmail.com and crashes entire server

[vedantroy]

When we run await fetch("https://gmail.com"), in a loader, we get this error:

    Error: Premature close

        at TLSSocket.<anonymous> (/tmp/remix/node_modules/@remix-run/web-fetch/src/fetch.js:343:32)
        at TLSSocket.emit (node:events:532:35)
        at node:net:687:12
        at TCP.done (node:_tls_wrap:580:7)

On its own, this is no massive issue. The problem is that the server crashes after this, rendering it incapable of handling new requests.

I'm seeing this error occasionally when I am trying to use fetch and get 301 responses. My fetch is already wrapped in a try/catch so I'm not sure how to properly catch this error.

Downgrading to ~1.4.0 fixes the immediate issue, but a longer term fix is necessary.

Probably happened when we moved from node-fetch to @remix-run/web-fetch in #2736

[BenMcH]

This has bugs but is allowing me to work around the issue in my specific case.

const fetchWithManualRedirect = (url, opts) => fetch(url, opts = {}).then(res => {
  return [301, 302].includes(res.status) ?
    fetchWithManualRedirect(res.headers.get('location'), {...opts, redirect: 'manual'})
    : res
})

The bug appears to be within the fetch package, specifically around how the redirect options function.

[jenseng]

Ran into the same issue a couple months back and the same workaround worked for me (i.e. don't automatically follow redirects).

In my case, the server in question was sending a redirect response w/ chunked transfer encoding. I think this might be the commit that needs to be backported (but it might not be trivial since afaik @remix-run/web-fetch is based on 2.x): node-fetch/node-fetch#1222

I am also running into this same error now when requesting a pdf resource with fetch. Using redirect: 'manual' like previous suggestions causes CORS issues, so I haven't been able to identify a workaround yet outside of downgrading.

[BenMcH]

Oh, @jacob-ebey, I didn't mean for this issue to actually be closed 🤦‍♂️. The integration of the updated fetch package with remix will fix this one.

Sorry, I thought my phrasing in my PR wouldn't have triggered github's auto-close feature.

[raymclee]

still having the error after upgrading the version to 1.6.5

[machour]

@raymclee 1.6.5 was released before this got merged. It will be shipped in the next release.
@BenMcH we are used to close issues/PRs as soon as they are fixed in git, without waiting for a release, so nothing to worry about here :)

/cc @jacob-ebey for confirmation of both my claims

My concern is that the web-fetch package failed to release and wasn't brought into remix. A release today would not fix the issue.

Re-opening for visibility

[BenMcH]

@mcansh just got the web-fetch release cut, so if you delete package-lock.json and your node modules folder, you'll pull in @remix-run/web-fetch v4.2.0 which has the fix for this thread!

[kiliman]

This also appears to work:

npm up @remix-run/web-fetch@latest --no-package-lock

[asinan007]

Hi @BenMcH i know this seems to be fixed in @remix-run/web-fetch v4.2.0

Hoping this get resolved soon!

Hi @mcansh @BenMcH I'm having the same issue here, for some reason 4.3.2 started to fail/crash with 301 responses.

[danielemery]

+1 also having this issue

On the first route of the first project I'm trying with remix so not a really good look 😓

The PR looks good to me, would be great to get an approval!
