Crontab not triggering execution when installed during AWS CentsOS EC2 bootstrap

I am deploying a cron file abcd.cron in /etc/cron.d/ location during EC2 bootstrap time using Cloudformation user-data(Uses clod-init). This is not triggering the execution(Checked /var/log/cron log file) unless I modify the cron file /etc/cron.d/abcd.cron (updating time). I tried to restart crond service in the cloud-init section after cron file copy, but that didn't help.

Is there a way to fix this issue during bootstrap time without manual modification ?

Try like this in your CloudFormation:

crontab -l > /tmp/mycrontab
echo '0 * * * * ls -la' >> /tmp/mycrontab
crontab /tmp/mycrontab
