react-native-image-picker uri to file to node js backend

I am working on a react-native social app and trying to upload a post image from react-native using react-native-image-picker and typescript. I am able to get Image uri but have to create file/blob to send it to node js backend

const choosePhotoFromLibrary = async () => {    await launchImageLibrary({      mediaType: "photo",      selectionLimit: 1,      includeBase64: true    })      .then(({assets}: any) => {        setImage(assets[0].uri);      })      .catch((err) => {        console.log(err);      });  };

This is my react-native-image-picker function to select image from gallery. I have tried to convert uri to blob and then to file like

const blobuploadImage = async (imageUri) => {    const response = await fetch(imageUri);    const blob = await response.blob();    console.log(blob)    return blob;  };

const uploadImage = async () => {    const formData = new FormData();    const blob = await blobuploadImage(base.uri);    var file = new File([blob], `Image.${base.type.split("/")[1]}`, {      type: base.type,    });    formData.append("file", file);    return await dispatch(uploadFile({ token, formData }))  };

Image file is empty or corrupted that stored on backend but I have tested backend Api with postman uploading Image. Its working fine then
