Production : Solace PubSub+ connector version 1.3.0 Connector Issue

[teredpus]

Valid Json is published to solace using MuleSoft Solace PubSub+ connector version 1.3.0 but in subscribing API we are facing empty input error.
The error seems to be intermittent and could see successful transactions for same operation.

Have attached the Worker logs . PFB error trace :

We tried enabling debug logs and could notice that payload is getting emptied in publish connector "attLen=3"
