Cannot read property 'sendingStatus' of null or InvalidParameters in use sendFileMessage

use @sendbird/chat
got an error “Cannot read property ‘sendingStatus’ of null” or “InvalidParameters” when use channel.sendFileMessage()
use expo, expo-image-picker, expo-file-system

let result = await ImagePicker.launchImageLibraryAsync({
        mediaTypes: ImagePicker.MediaTypeOptions.All,
        allowsEditing: true,
        aspect: [4, 3],
        quality: 1,
        base64: true,
const fileInfo = await FileSystem.getInfoAsync(result.uri)
      const localUri = result.uri;
      const filename = localUri.split("/").pop();
      const match = filename ? /\.(\w+)$/.exec(filename) : "";
      const type = match ? `image/${match[1]}` : `image`;

      function dataURItoBlob(dataURI) {
        // convert base64/URLEncoded data component to raw binary data held in a string
        let byteString;
        if (dataURI.split(',')[0].indexOf('base64') >= 0)
          byteString = atob(dataURI.split(',')[1]);
          byteString = unescape(dataURI.split(',')[1]);

        // separate out the mime component
        let mimeString = type;

        // write the bytes of the string to a typed array
        let ia = new Uint8Array(byteString.length);
        for (let i = 0; i < byteString.length; i++) {
          ia[i] = byteString.charCodeAt(i);

        return new Blob([ia], {type:mimeString});

      const blob = dataURItoBlob(result.base64)
      const newFile = new File([blob], filename, { type });

return props.onSend([{
        size: fileInfo.size,
        file: newFile,
        name: filename,
        base64: `data:image/jpg;base64,${result.base64}`,
        fileUrl: result.uri,
        width: result.width,
        height: result.height,

try use file, base64, fileUrl, blob, fileInfo all of them not working… Please help, what I do wrong?
