Site backup failed corrupt json file

Full Backup failed. The system failed to parse the JSON stream data "" for the caller "Cpanel::Wrap::send_cpwrapd_request" because of an error: malformed JSON string, neither tag, array, object, number, string or atom, at /usr/local/cpanel/Cpanel/JSON.pm line 123. I'm new to server side config. How do I fix this issue? I would appreciate any help:) System specs OS: Centos 6.10 Memory: 2G RAM Error Log: [2017-05-12 11:59:50 -0700] warn [builddovecotconf] The "/etc/dovecot/ssl/dovecot.crt" certificate fetch failed due to an error: (XID jw8yw8) The system cannot find a file named "/etc/dovecot/ssl/dovecot.crt". at /usr/local/cpanel/Cpanel/AdvConfig/dovecotSNI.pm line 68.
