Fetch cannot load MY_PATH

I'm currently stuck with this error cross all integration tests:

TypeError: Fetch API cannot load: <MY_PATH>

TypeError: Fetch API cannot load: <MY_PATH>

I'm using SELF

const res = await SELF.fetch(req.url, {
  method: req.method,
  headers: req.headers,
  body: JSON.stringify(req.body),
});

const res = await SELF.fetch(req.url, {
  method: req.method,
  headers: req.headers,
  body: JSON.stringify(req.body),
});

couldn't find anything via googling, has anyone encountered this too?

What does your vitest.config.ts look like?

import { defineWorkersConfig } from "@cloudflare/vitest-pool-workers/config";

export default defineWorkersConfig({
  test: {
    dir: "./src/routes",
    reporters: ["html", "verbose"],
    outputFile: "./.vitest/html",
    alias: {
      "@/": new URL("./src/", import.meta.url).pathname,
    },
    pool: "@cloudflare/vitest-pool-workers",
    poolOptions: {
      singleWorker: true,
      workers: {
        wrangler: { configPath: "./wrangler.toml" },
      },
    },
    testTimeout: 60_000,
    teardownTimeout: 60_000,
  },

Is <MY_PATH> just a pathname or is it a full URL? You'll need to pass full URLs with protocols to SELF.fetch(). The protocol/host is ignored, but the value must be a valid URL.

oh I just replaced it, it prints the correct paths

TypeError: Fetch API cannot load: /v1/apis.listKeys?apiId=test_2gV5Kah3DoEdrsmrKf3bnFc89AJZ

TypeError: Fetch API cannot load: /v1/apis.listKeys?apiId=test_2gV5Kah3DoEdrsmrKf3bnFc89AJZ

as example ok let me try full urls this used to work with unstable_dev, so I thought it would work here too

MrBBot•9mo ago

Yep, you'll need to make sure you're passing a full URL, something like https://placeholder/v1/apis/... Here, SELF is a service binding, which requires full URLs

gotcha, that seems to work on to the next error 😅
