Hi, We are using elastic search in our backend hosted on AWS. And our backend is in Java. We have seen a pattern where queries start failing for a brief period of time with the following error: `cannot write time value xcontent for unknown value of type class java.util.Date` This auto resolves itself after some time. But keeps happening every once in a while. Could you help me figure out what the issue is? Cheers, Sajjan ---

Are you using AWS Elasticsearch service or self hosting on AWS? Which version are you using? Is there anything relevant in the Elasticsearch logs? ---

We are using AWS hosted Elastic Search java sdk version: 7.8.1. The logs only have this xcontent error. Nothing relevant unfortunately. But the error seems to generally happen when we do a server deployment. So, could be some sort of an initialization issue? ---

If you are using AWS Elasticsearch it is hard to help as they are using a custom fork with custom plugins. I would recommend contacting AWS support. ---

Hi Christian, I just checked with my team. We don't infact use AWS elastic search because they don't support 7.8.1 version and we didn't want to go back. Sorry for the confusion! I really need help solving this! ---

Then you should have access to the Elasticsearch logs. Is there anything relevant there around the times you have experienced these problems? ---

I haven't seen the exact logs printed around the time of the error. Will get the logs from elastic search for that time. ---

Are you using any third-party plugins? Do you have any non-standard configuration? ---

No, we are not. I can't find any relevant logs around the same time when the error occurs in Elastic Search. I see an error n the ES logs but might be unrelated. ---
