Hi,  
I am entirely new to Logstash and elasticsearch  
Currently I am facing a problem creating LS pipeline using kafka input which receives an avro message.

 ![LS_Error](https://us1.discourse-cdn.com/elastic/original/3X/b/7/b7d8c7fb11419c4931048721d124e6e79e7b69b2.JPG)

The following is the configuration that is being used.

input {  
kafka{  
bootstrap\_servers =\> "localhost:9092"  
group\_id =\> "logstashgroup"  
codec =\> {  
avro =\> {  
schema\_uri =\> 'path\to\avro\schema\file.avsc'  
}  
}  
value\_deserializer\_class =\> "path\to\avro\deserializer\class\AvroDeserializer.class"  
topics =\> "kafka\_topic1"  
}  
}  
output {  
stdout { }  
elasticsearch { hosts =\> "localhost:9200"  
index =\> "kafka\_topic1\_index"}  
}

Installed:  
logstash-5.5  
logstash-input-kafka 5.1.8  
logstash-output-elasticsearch 7.3.6  
logstash-codec-avro 3.2.1  
elasticsearch-5.5

Any help from the community is a motivation !

Thanks.
