Batch Upload session in Mobile Browser Error
Hi, I have build an dropbox uploader in the web using the await dbx.filesUploadSessionStart and it works great in the desktop and mobile.
However It causes an error in the mobile browser if we select the files only from google drive. This error happens only in the mobile browser. There is a TypeError, Failed to fetch error, which I guess it might be cors issue ?
May I know how I can fix this ?
Thank you.
Thanks! It looks like this is a bug in Chrome Android/Google Drive. There's a post about this here: https://stackoverflow.com/questions/62714319/attached-from-google-drivecloud-storage-in-android-file-gives-err-upload-file

- It got error in the filesUploadSessionStart..........var file = fileInput.files[i];var filename = fileInput.files[i].name;try {let res = await dbx.filesUploadSessionStart({contents: file,close: true,});}catch(err) {document.getElementById("v1").value += "error "+err+" : ";}var obj = res;var str = JSON.stringify(obj);...

- Since its in mobile, there is no console for me to debug, but here is the error I can get -> TypeError: Failed to fetch

Thanks for the additional information. I don't see anything clearly wrong in your code, and since it only happens with files from Google Drive, it sounds like there's something unique to how the files are returned from Google Drive.
Can you try using Chrome Remote Debugging to see if you can get a more specific error?
