Hi,  
I have a problem with my Logstash Component. When starting I get the following failure and can't find helpful information online. I use a SLES 15 with Logstash 7.16.1 and OpenJDK11.

```auto

```

May one of you have an idea, what the issue could be?

Thanks for your help

I found the Problem. There was a wrong symbol in the logstash.yml File. The certificat had ["cert"], but the sytem wants only "cert"

@tobias.greis can you say exactly what setting you had the problem with? I would expect you to get the message

> Your settings are invalid. Reason: Setting "..." must be a String. Received: ["..."] (Array)

for that.

In the Logstash Configurationxpack certificate\_autjority part.

Wrong:

```auto
xpack.monitoring.elasticsearch.ssl.certificate_authority: ["path/to/cert"]

```

Correct:

```auto
xpack.monitoring.elasticsearch.ssl.certificate_authority: "path/to/cert"

```

With 7.16.2 I get

> Your settings are invalid. Reason: Setting "xpack.monitoring.elasticsearch.ssl.certificate\_authority" must be a String. Received: ["path/to/cert"] (Array)
