I am encountering an intermittent issue in Apache Solr where executing queries sometimes results in a "parsing error" response. I have a Java Spring backend application that communicates with an Apache Solr server hosted on a Dataproc cluster. The communication is established using the HttpURLConnection in my Java code. The error occurs sporadically and does not consistently reproduce.

],

"code": 200
}
}

I am using Apache Solr version 8.1.1. While investigating the issue, I came across two known bugs in Apache Solr that mention similar parsing errors:
Considering the similarity of the parsing error I am encountering, I suspect it may be related to one of these known bugs. However, I would like to confirm if other users have experienced a similar issue or if there are any known workarounds or solutions available.
Any insights or suggestions would be greatly appreciated. Thank you!
