I'm running packetbeat version 7.10.1;  
Looking at its logs I see

```auto
2020-12-25T23:08:29.956Z WARN http/http.go:545 Fail to parse HTTP parameters: parse "response\"}}\nPOST /_bulk": net/url: invalid control character in URL

```

That's the request coming from when I work with Kibana, but in anycase, the same error for any other requests such as

Another example of URL having the same error

```auto

```

Here's the `packetbeat.yml` file content:

```auto
packetbeat.interfaces.device: any
packetbeat.interfaces.snaplen: 1514
packetbeat.interfaces.type: af_packet
packetbeat.interfaces.buffer_size_mb: 100

```

Any idea what could be the problem?
