Logstash JSON parser error

Thanks All for your reply.

I'm getting this warning only at the LS start-up, post-start, it is not getting displayed. But the source data keeps on passing through the LS. Not sure, Why the same is not coming for all the source data.

The same issue is not occurring in the LS version 7.10.2 for the same source data. Whereas the LS version 8.4.0 only throws this warning.

Please share your expertise.
