Cron Error: bad username; while reading /etc/cron.d file on Linux

One of our client was facing issue while running the cron job, on checking the following error finds in his cron job log file /var/log/cron.log: 

Jan 01 11:59:01 server cron[7510]: Error: bad username; while reading 

He has the job entry as follows to run at 00:50 every day for root user:

50 0 * * * /etc/cron.d/backups

He was getting this error because he forgot to set name of the user to run a cron job:

1 2 3 4 5 USERNAME /path/to/command arg1 arg2

The correct syntax will be as follows for root user to run a cron job at 00:50 every day:

50 0 * * * root /etc/cron.d/backups

To run as cppl user:

50 0 * * * cppl /etc/cron.d/backups
