Lab - Shard a Collection - New

I am getting below error while unzipping the .tgz file. Please suggest how to resolve this issue.
I have already tried doing multiple times by removing all and do it again but still same error.
vagrant@m103:~ ls data products.json products.json.tgz test vagrant@m103:~ rm products.json
vagrant@m103:~ ls data products.json.tgz test vagrant@m103:~ tar zxvf products.json.tgz

gzip: stdin: unexpected end of file
tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now


May be the downloaded file is not complete?
Is it not available on your /dataset?
Please check our forums

function download_dataset() {
echo “Downloading Dataset”
curl -s -o products.json.tgz
tar -xzvf products.json.tgz -C /dataset
rm -rf products.json.tgz
