Anyone know why I get this error?

I'm using a library (ethers.js) that uses this library to make requests.

When I try to run a request from my node js server, I'm getting this error:

serverError: TypeError: Referrer "client" is not a valid URL.
      at new Request (/Users/ami/Sites/r3lic-studios/client/node_modules/undici/lib/fetch/request.js:230:25)
      at new Request (/Users/ami/Sites/r3lic-studios/client/node_modules/@miniflare/core/src/standards/http.ts:407:13)
      at upgradingFetch (/Users/ami/Sites/r3lic-studios/client/node_modules/@miniflare/web-sockets/src/fetch.ts:20:19)
      at WebSocketPlugin.<anonymous> (/Users/ami/Sites/r3lic-studios/client/node_modules/@miniflare/core/src/standards/http.ts:907:21)

Not sure if the source of the problem is this library, but any thoughts on this would be very helpful, thanks.

The Request constructor is not entirely spec-compliant because node.js has no concept of "origin". If you use a partial URL, or a path, an error will occur because there's no base url (defaulting to the origin in browsers).

// Browsers
new Request('http://localhost', { referrer: 'client' }).referrer
// => "https://github.com/nodejs/undici/discussions/client" 

// Undici
new Request('http://localhost', { referrer: 'client' }).referrer
// => Uncaught TypeError: Referrer "client" is not a valid URL.

I noticed this a little while ago, but there's nothing undici can realistically do (other than remove referrer entirely - similar to Deno).

If you can set the referrer yourself, you can hack-fix this:

new Request(
  'http://localhost',
  { referrer: new URL('client', 'http://localhost').toString() }
)
