What steps will reproduce the bug?

I write TypeScript which Node doesn't read so I write esbuild thefile.ts | node --input-type=module - to strip the TS typings and pass the ESM directly to Node. This works 💯👍

However, if the code uses import.meta.url such as const __dirname = path.dirname(fileURLToPath(import.meta.url)); this throws:

node:internal/process/esm_loader:74
    internalBinding('errors').triggerUncaughtException(
                              ^

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string or an instance of URL. Received undefined
    at new NodeError (node:internal/errors:363:5)
    at fileURLToPath (node:internal/url:1372:11)
    at file:///home/today/_/work/acorn-macros/test/style.macro/[eval1]:12:32

    at async node:internal/process/execution:49:24
    at async loadESM (node:internal/process/esm_loader:68:5) {
  code: 'ERR_INVALID_ARG_TYPE'
}

Because import.meta.url is undefined. Shouldn't it be "file:///home/today/_/work/acorn-macros/test/style.macro/[eval1]" since that's what's shown in the stacktrace?

How often does it reproduce? Is there a required condition?

Using import.meta.url when accepting a script via stdin.

> echo "console.log(import.meta.url)" | node --input-type=module
undefined

What is the expected behavior?

The url property is "file:///home/today/_/work/acorn-macros/test/style.macro/[eval1]"

> echo "console.log(import.meta.url)" | node --input-type=module
file:///the/real/path/[eval1]

As a workaround you can hack this in via:

if (import.meta.url === undefined) {
  try {
    throw new Error();
  } catch (e) {
    const url = /at (.+):\d+:\d+$/.exec(e.stack.split('\n')[1])[1];
    console.log('Reset to', url); // Logs "Reset to file:///home/today/_/work/acorn-macros/test/style.macro/[eval1]"
    import.meta.url = url;
  }
}
// ... now carry on as normal, no errors: 
const __dirname = path.dirname(fileURLToPath(import.meta.url));

What do you see instead?

Throws :(
