I hope that helps a little?

Are you seeing a "caused by" section of the stack trace that comes after what you posted? That should show the relevant pulsar package, if pulsar is the problem. If not, do you know which endpoint is causing the issue? The easiest way to figure it out is if we can reproduce the problem reliably.
t
Sorry its quite difficult to find as its json logged over datadog... This is the full json not sure if that helps?

I'm not familiar with datadog, but I'm guessing that the 
endOfBatch
being false could mean that there is another part of the exception. It would be the next set of lines after this blob. Do you know which endpoint is triggering the error?
