Cannot read property 'ExpoImageManipulator' of undefined

I want to compress image using expo-image-manipulator. I followed documentation Expo-ImageManipulator. Everything seems fine but i get "Cannot read property 'ExpoImageManipulator' of undefined". Have you ever faced this error?

import { manipulateAsync } from "expo-image-manipulator";

  const manipResult = async (imageUri) =>
      await manipulateAsync(
      imageUri,
      [{ resize: { width: 640, height: 480 } }],
  );

import * as ImageManipulator from "expo-image-manipulator";

Importing your ImageManipulator like this worked for me.

And also check if you have correct version of ImageManipulator for your sdk

Sorry, i don't have an enough reputation so can't do comment, only answer... Did you try do their examples with all params for manipulateAsunc?

const _rotate90andFlip = async () => {
    const manipResult = await manipulateAsync(
      image.localUri || image.uri, // maybe you don't have this value
      [
        { rotate: 90 },
        { flip: FlipType.Vertical },
      ],
      { compress: 1, format: SaveFormat.PNG } // or need add this
    );
    setImage(manipResult);
  };
