I have the below error:

[root@~]# traceroute -s 'publicIP' 8.8.8.8
traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 60 byte packets
**bind: Cannot assign requested address**

But when i did not enter source, it works fine:

Please advice me on resolution.
Do let me know if you need more information.
Thanks in advance :)

You need to type traceroute -s with addresses which directly assign to any interfaces on your server.

You can type any of this addresses from your output of ip a:

192.168.111.xyz
192.168.111.xyzz

But not real public ip because it has assigned to your other device (e.g. router).

See man traceroute:

-s source_addr, --source=source_addr

Chooses an alternative source address. Note that you must select the address of one of the interfaces. By default, the
address of the outgoing interface is used.
