Hi, my elasticsearch 7.7.1 sometimes returns `encoded bytes are incorrect length` error with 400. It's only sometimes, can you tell me the meaning? What can be couse of it?

Can you provide a bit more information please.  
What is the full error? Is there anything in the Elasticsearch logs? What client is receiving this error?

Elastic log doesn't how anything. I am using elasticsearch-js client and that returns

```
