Could not resolve a bunch of packages

Hi, I am trying to make a simple thing to send requests thru an authenticated proxy, but for some reason when I try to build, I get a bunch of errors.

X [ERROR] Could not resolve "worker_threads"

    node_modules/undici/lib/fetch/constants.js:3:57:
      3 │ ... MessageChannel, receiveMessageOnPort } = require('worker_threads')
        ╵                                                      ~~~~~~~~~~~~~~~~

  The package "worker_threads" wasn't found on the file system but is built into node. Are you trying 
to bundle for node? You can use "platform: 'node'" to do that, which will remove this error.

I get this error but for async_hooks stream/web util/types perf_hooks diagnostics_channel and of course, worker_threads

This started to happen after I added this snippet

function getAgent(env: Env): ProxyAgent {
    const agent = new ProxyAgent({
        uri: env.proxyHost,
        token: `Basic ${Buffer.from(env.proxyAuth).toString('base64')}`,
    });

    return agent;
}

function getAgent(env: Env): ProxyAgent {
    const agent = new ProxyAgent({
        uri: env.proxyHost,
        token: `Basic ${Buffer.from(env.proxyAuth).toString('base64')}`,
    });

    return agent;
}

wrangler.toml has node_compat set to true I am still having this problem. It seems to only happen when i import undici

Workers doesn’t support threads or Undici, even with node_compat

Oh. How could I use a proxy then? I was told I should use undici to send proxy requests with workers…

Hello, I’m Allie!•17mo ago

You can use proxies over HTTP(S)

userOP•17mo ago

How so? I specifically need to be able to use auth with the proxy, so if cf can’t support that, i’m gonna have an issue xd

Hello, I’m Allie!•17mo ago

Nvm, I've apparently used a weird proxy. Looks like it should be able to work, but you may have to write your own proxy connector(since you have to use Workers' fetch rather than Undici), and you can't use threads.
