Is anyone using `"@aws-sdk/client-s3"` ?

Is anyone using "@aws-sdk/client-s3" ? I currently do:

    const s3Client = new S3Client({
        region: "auto",
        endpoint: `https://${process.env.CLOUDFLARE_ACCOUNT_ID}.r2.cloudflarestorage.com`,
        credentials: {
            accessKeyId: process.env.CLOUDFLARE_R2_BUCKET_ACCESS_KEY_ID,
            secretAccessKey: process.env.CLOUDFLARE_R2_BUCKET_SECRET_KEY_ID,
        },
    })

    const s3Client = new S3Client({
        region: "auto",
        endpoint: `https://${process.env.CLOUDFLARE_ACCOUNT_ID}.r2.cloudflarestorage.com`,
        credentials: {
            accessKeyId: process.env.CLOUDFLARE_R2_BUCKET_ACCESS_KEY_ID,
            secretAccessKey: process.env.CLOUDFLARE_R2_BUCKET_SECRET_KEY_ID,
        },
    })

Any my workers throws a 500 with: Cannot convert object to primitive value

I have a similar code for my pages function, and it is working fine.

const S3 = new S3Client({
    region: "auto",
    endpoint: `https://${ACCOUNT_ID}.r2.cloudflarestorage.com`,
    credentials: {
        accessKeyId: ACCESS_KEY_ID,
        secretAccessKey: SECRET_ACCESS_KEY,
    },
});

const S3 = new S3Client({
    region: "auto",
    endpoint: `https://${ACCOUNT_ID}.r2.cloudflarestorage.com`,
    credentials: {
        accessKeyId: ACCESS_KEY_ID,
        secretAccessKey: SECRET_ACCESS_KEY,
    },
});

Are you getting this error when running any operation?

cosbgnOP•7mo ago

Yes this is just at the beginning of my code, so before any op I also double checked all env vars and they are logged correctly You import it like this right: import { S3Client } from "@aws-sdk/client-s3";

Maybe I need nodejs_compat it's the only difference I see Nope same error. So weird! tried also by pinning v3.600

Hard@Work•7mo ago

Are all of your bindings strings? That's my first guess, that for some reason, it is being given an object that it tries(and fails) to cast into a string

cosbgnOP•7mo ago

I don't use bindings

Hard@Work•7mo ago

For process.env?

cosbgnOP•7mo ago

Those are env variables

cosbgnOP•7mo ago

Set here

Hard@Work•7mo ago

Hm... running it locally, does it throw the same error?

cosbgnOP•7mo ago

No locally it works perfectly also, when I do:

await log(`${process.env.CLOUDFLARE_ACCOUNT_ID.substring(0,5)}-${process.env.CLOUDFLARE_R2_BUCKET_ACCESS_KEY_ID.substring(0,5)}-${process.env.CLOUDFLARE_R2_BUCKET_SECRET_KEY_ID.substring(0,5)}`)

await log(`${process.env.CLOUDFLARE_ACCOUNT_ID.substring(0,5)}-${process.env.CLOUDFLARE_R2_BUCKET_ACCESS_KEY_ID.substring(0,5)}-${process.env.CLOUDFLARE_R2_BUCKET_SECRET_KEY_ID.substring(0,5)}`)

I get the strings as expected, also in prod

Hard@Work•7mo ago

Does the error show which exact line it is failing on?

cosbgnOP•7mo ago

Yes but it's minified so it's messed up. But I tried with console.log(1) and console.log(2) just before and after new S3Client({ and log(2) doesn't show up so it's somewhere in new S3Client()

Hard@Work•7mo ago

Yeah, I'm trying to figure out whether it is failing on the endpoint, or the credentials Let me try spinning a repro, and seeing if I can replicate your error

cosbgnOP•7mo ago

Hard@Work•7mo ago

Wait, it is Nuxt... Not Next Ugh, rebuilding

cosbgnOP•7mo ago

nuxt deserves more love such a nice tool But yeah the whole app is bundled in there, so it's hard to reproduce

Hard@Work•7mo ago

Can you disable minification?

cosbgnOP•7mo ago

on cl dashboard?

Hard@Work•7mo ago

No, in Nuxt

cosbgnOP•7mo ago

I don't think, I'm googling it, but I think server code it's always minified I've also added toString() but doesn't help:

        endpoint: `https://${process.env.CLOUDFLARE_ACCOUNT_ID.toString()}.r2.cloudflarestorage.com`,
        credentials: {
            accessKeyId: process.env.CLOUDFLARE_R2_BUCKET_ACCESS_KEY_ID.toString(),
            secretAccessKey: process.env.CLOUDFLARE_R2_BUCKET_SECRET_KEY_ID.toString(),
        },

        endpoint: `https://${process.env.CLOUDFLARE_ACCOUNT_ID.toString()}.r2.cloudflarestorage.com`,
        credentials: {
            accessKeyId: process.env.CLOUDFLARE_R2_BUCKET_ACCESS_KEY_ID.toString(),
            secretAccessKey: process.env.CLOUDFLARE_R2_BUCKET_SECRET_KEY_ID.toString(),
        },

I'm pretty sure creds are correct (also form the logs screenshotted) from the logs, I think it happens here: export const defaultUserAgent = ({ serviceId, clientVersion }: DefaultUserAgentOptions): Provider<UserAgent> => {

So some of this in workers is an object and not a string:

[`os/${platform()}`, release()]
["md/nodejs", `${versions.node}`]
[`exec-env/${env.AWS_EXECUTION_ENV}`]
[`app/${appId}`]

[`os/${platform()}`, release()]
["md/nodejs", `${versions.node}`]
[`exec-env/${env.AWS_EXECUTION_ENV}`]
[`app/${appId}`]

I just don't get why it happens to me and not everyone else

Hard@Work•7mo ago

Huh... https://e9832717.my-nuxt-app-6jh.pages.dev/hello

cosbgnOP•7mo ago

I'm getting the same

Hard@Work•7mo ago

Yeah, so it isn't just a you issue...

cosbgnOP•7mo ago

yes but S3Client is fairly used in workers and I can't find a single mention of this maybe is nuxt doing some polyfill to fix node

Hard@Work•7mo ago

I'm guessing maybe it is a Nuxt + S3 issue Let me see if I can get a bit closer

cosbgnOP•7mo ago

🙏

Hard@Work•7mo ago

Found it!

cosbgnOP•7mo ago

OMG

Hard@Work•7mo ago

It appears that Nuxt is using unenv to smooth over differences in runtimes And one of the things it does on build is replace imports from os with a proxy that doesn't appear to be working correctly Looking at the unminified code isn't very enlightening, but yeah

cosbgnOP•7mo ago

Any solution?

Hard@Work•7mo ago

Disable unenv somehow? Not entirely sure, probably something you want to flag either to the Nuxt or unenv team

cosbgnOP•7mo ago

Thanks a ton for the investigation super helpful.

Hard@Work•7mo ago

Sorry I couldn't do more there. Tbh, I don't do much(if anything) in Nuxt, so I might not be the best person for this kind of thing

cosbgnOP•7mo ago

It's great I now know where to go Thanks a ton
