Bad id for repo: exam repo, byte = 4 --> yum repolist error

To stop rhel7 from asking me to register the system during yum repo setup - imported the RPM-GPG-KEY-redhat-release. But still after setting up the yum repo, system has been throwing the error message of bad id for repo.

[root@server1 Packages]# yum repolist
Loaded plugins: langpacks, product-id, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

[root@server1 Packages]# cat /etc/yum.repos.d/localcoverage.repo
