TypeError: The "iterable" argument must be an instance of Iterable. Received an instance of ReadableStream

[jasonChen1982]

Reproduction

Steps to reproduce the behavior:

    const file = fileFromSync(filePath);
    const formData = new FormData();
    formData.append('file', file, path.basename(filePath));

1. I use upon code in electron, but get a TypeError: The "iterable" argument must be an instance of Iterable. Received an instance of ReadableStream
2. maybe is there wrong ?
   
3. can you tell me node-fetch can work in electron (which has browser\node both)

Expected behavior

If ReadableStream is a native chrome stream, then you probably have to add a polyfill for making them async readable.

ReadableStream.prototype[Symbol.asyncIterator] ??= async function* () {
  const reader = this.getReader()
  try {
    while (true) {
      const {done, value} = await reader.read()
      if (done) return
      yield value
    }
  }
  finally {
    reader.releaseLock()
  }
}

yeah, thanks @jimmywarting , I get your mean. right, it is fetch-blob had a little bit unrigorous check. I hack it outside and then it work correct.

if (!globalThis.ReadableStream) {
  // `node:stream/web` got introduced in v16.5.0 as experimental
  // and it's preferred over the polyfilled version. So we also
  // suppress the warning that gets emitted by NodeJS for using it.
  try {
    const process = require('node:process')
    const { emitWarning } = process
    try {
      process.emitWarning = () => {}
      Object.assign(globalThis, require('node:stream/web'))
      process.emitWarning = emitWarning
    } catch (error) {
      process.emitWarning = emitWarning
      throw error
    }
  } catch (error) {
    // fallback to polyfill implementation
    Object.assign(globalThis, require('web-streams-polyfill/dist/ponyfill.es2018.js'))
  }
}
