Hello, I have many requests in the search and multi-search endpoints returning "Internal server error. Please check your application server logs for more details and contact Elastic support if the problem persists".

What's happening?

Update: I used the flag --diagnostic-report and saw all the logs.. however I can't find any reference to these internal errors

I can't attach the logs here

I had an issue in the JSON.

The filter was:

```auto
"filters" : {
	"all": [
		{ "idrubro": 10 },
		{ }
	]
}

```

Removing the empty { } solved the problem
