    Bucket: ...,
    Key: ...,
    Expires: 60 * 60 * 2, // Expires in 2h
    UploadId: uploadId,
    PartNumber: 1
})

split -b 50000000 test.mp4

I also tried using POST method. And adding content type but still got mismatch signature

Turns out I need to set the signature version to 4

const s3 = new AWS.S3({ signatureVersion: 'v4' });
