I just got both Kibana and Elasticsearch up and running as a windows service and now i want to build a very basic logstash pipeline to figure how it will perform sending the results to Elasticsearch so that i can make sure the pipeline really works well, below are my config and the error message.I also checked both kibana and Elasticsearch on browser, logging in with these credentials. Feeling stuck, any help is appreciated

# **logstash.conf**

```auto
input { stdin { } }
output {
  elasticsearch { hosts => ["localhost:9200"] index => "test.logstash" user => "elastic" password => "=Slkd9*T39wyNxw175bK" }
  stdout { codec => rubydebug }
}

```

# **cmd commands:**

`D:\logstash-8.12.2-windows-x86_64\logstash-8.12.2\bin>logstash -f D:\logstash-8.12.2-windows-x86_64\logstash-8.12.2\bin\logstash.conf`

# **error message:**

Hi @Abdulberk, Welcome to the community...

Common error... CD to the home directory and run from there .. logstash needs to that relative path to bin see [here](https://www.elastic.co/guide/en/logstash/current/running-logstash-windows.html#running-logstash-windows-manual)

In your case

```auto
PS> cd D:\logstash-8.12.2-windows-x86_64\logstash-8.12.2
PS> .\bin\logstash.bat -f .\bin\logstash.conf

```

BTW typically do not put the `.conf` file in the `bin` directory typically in the `config` directory

Hi @stephenb, thank you so much for your reply but it didnt work either, literally followed the same steps you mentioned, looked up the official guide as well.  
Even moved the conf file to config folder and tried to run it as Admin via PowerShell like the one below:

```auto
PS C:\Windows\system32> cd D:\logstash-8.12.2-windows-x86_64\logstash-8.12.2
PS D:\logstash-8.12.2-windows-x86_64\logstash-8.12.2> .\bin\logstash.bat -f .\config\logstash.conf

```

This error suggests that may there is something wrong in your configuration, maybe some encoding issues?

It is identifying that you may have something like this somewhere in your config file.

Where did you edit this file? I suggest that you recreate it on a editor like Notepad++.

I deleted the previous one and recreated on notepad++. Same error.

Also how about trying one of the default pipelines... don't open and edit let's just see if it will run... it will just open a port 5044

```auto
PS C:\Windows\system32> cd D:\logstash-8.12.2-windows-x86_64\logstash-8.12.2
PS D:\logstash-8.12.2-windows-x86_64\logstash-8.12.2> .\bin\logstash.bat -f .\config\logstash-sample.conf

```

yeah, just tried it now either, didnt event open or change anything inside, but still the same error message, i dont really know what to do, maybe i should also consider configuring this pipeline on Elastic Cloud, which i think it will just do fine this time 🥴

This is a strange error. The [PluginType is an enum](https://github.com/elastic/logstash/blob/92b20bc18418b9ec75f0b31b3a141c0fc420338f/logstash-core/src/main/java/org/logstash/plugins/PluginLookup.java#L145) with the values INPUT, FILTER, OUTPUT, CODEC. logstash is trying to load plugin\_aliases.yml [here](https://github.com/elastic/logstash/blob/92b20bc18418b9ec75f0b31b3a141c0fc420338f/logstash-core/src/main/java/org/logstash/plugins/AliasRegistry.java#L174). At the point where the exception occurs it has already validated the checksum on the YAML!

There is a plugin\_aliases.yml under lib/pluginmanager/ (this is not the file that logstash reads). Looking at the code it is conceivable it could get an exception if that "input:" line contained something else, but hard to see how the corrupted yml file could get into the classpath and pass the checksum.

        with: ":plugin-uc: Elastic Agent"
      - replace: ":plugin-singular: Beat"

Ok So I just download Logstash  
Unzipped It  
Touched Nothing  
and it ran as expected

BUT I had to be very careful I actually had to unzip it twice as it hung up once... I did not notice that and when I tried to start I got a different bizarre error ....

So Perhaps cleanup ... download a new zip unzip and make sure it completes

```auto
PS C:\Users\stephenb\Downloads\logstash-8.12.2> .\bin\logstash.bat -f .\config\logstash-sample.conf

```

exceptionally strange.. i literally did whatever you did above in reply, downloading the zip again and only extract the folder inside so it will be accessible without going into another folder inside, even put it on C Drive this time.. I just screen recorded the steps I followed, excluding the download processes.

Yup Exceptionally Strange...

But again are you sure you let it all the way unzip... mine turned out to take much longer than I thought ...

Can you check the number of files does it match what I showed above?

Otherwise not sure what to tell you...

ok thanks anyway, and thanks to everyone who was trying to help me get out of the trouble. I think i will consider it in the future, as what i was exactly looking for was not really real-time data streaming utilizing logstash or something, since I just realized that Elastic Cloud has already integrations like PostgreSQL connector for "near real-time" streaming data from the source even if not real-time. Already established the connection between them and works like a charm now.
