Cannot getReader of ReadableStream

[robinsadeghpour]

Hey,

I cannot get the reader from the readableStream I get following Error:
Error: [TypeError: This stream has already been locked for exclusive reading by another reader]

I also have added the auto import for the polyfills to the root _layout.tsx as I use filebased routing.
import 'react-native-polyfill-globals/auto';

const res = await fetch("https://www.lotti.ai/api/lotti", {
        method: "POST",
        headers: {
          "Content-Type": "application/json",
          Connection: "keep-alive",
        },
        mode: "cors",
        body: JSON.stringify(message),
        "reactNative": { textStreaming: true }
      })

      const reader = res.body?.getReader();

I should also mention that the type for reactNative: {textStreaming: true} seems to not be detected correctly:

The solution is:
npm install web-streams-polyfill@3.2.1
Because the latest version of web-streams-polyfill (4.x) only has polyfill of ES5. But the repo is using ES6 polyfill.

@robinsadeghpour did you find a solution?

All solutions shared doesn't work. Body obj doesn't have stream support in hermes.
