AWSS3TransferUtilityErrorDomain Code=2 on ios

AWSS3TransferUtilityErrorDomain Code=2

enter image description here

getting this error when uploading reaches 100% on iOS while android is working fine.

I am using react-native-s3. but it seems to be an issue with sdk or my bucket policy but I don't know how to fix this.

More info: To upload, I am using CognitoCredentials, the region, IdentityPool, and sessionToken generated from our server.

EDIT: This only happens on iOS. Android is working fine.

In my case, the case for the issue was special symbols in the file name, in particular %. Filtering special symbols from the file name before uploading the file solved the issue.

Check your ARN at the time of adding policy to S3 bucket. It should be like

arn:aws:s3:::yourBucketName/*

if you are uploading in your bucket directly without any sub directory.

I know this is an old question, however it's better to write my situation and solution. In my iOS (Swift) project, I was trying to upload a picture after login (using Cognito) and I got this error:

Error Domain=com.amazonaws.AWSS3TransferUtilityErrorDomain Code=2 "(null)"

Everything seemed well on code below:

transferUtility.uploadData(
            data,
            key: "my-picture.png",
            contentType: "image/png",
            expression: expression,
            completionHandler: completionHandler).continueWith { (task) -> AnyObject? in
                if let error = task.error {
                    print("Error: \(error.localizedDescription)")
                    DispatchQueue.main.async {
                        print("Error on upload: \(error.localizedDescription)")
                    }
                }

                if let _ = task.result {
                    DispatchQueue.main.async {
                        print("Upload Starting!")
                    }
                }

                return nil;
        }

The solution is on AWS Amplify Storage documentation. As stated there, I should have written the key value like key: "private/{user_identity_id}/my-picture.png"

Maybe, it will help anybody in the future.

So it seems my problem was wrong region. I don't know why Android works though.

Typically this is an S3 bucket policy issue, permissions. Below is an example policy script for s3.

<key>AWS</key>
    <dict>
        <key>CredentialsProvider</key>
        <dict>
            <key>CognitoIdentity</key>
            <dict>
                <key>Default</key>
                <dict>
                    <key>PoolId</key>
                    <string>us-west-2:xxxxx</string>
                    <key>Region</key>
                    <string>USWest2</string>
                </dict>
            </dict>
        </dict>
        <key>S3TransferUtility</key>
        <dict>
            <key>Default</key>
            <dict>
                <key>Region</key>
                <string>**USEast1**</string>
            </dict>
        </dict>
    </dict>
