HI,

Error I am receiving in logstash logs is :

[2022-02-22T15:19:27,369][ERROR][logstash.codecs.json] JSON parse error, original data now in message field {:error=\>#\<LogStash::Json::ParserError: Unexpected character ('=' (code 61)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')  
at [Source: (String)"="; line: 1, column: 2]\>, :data=\>"="}

How i can debug this error . And how to find which pipeline is giving me this error.

Thanks.

Looks as if your JSON data is not JSON but simply an equals sign `=`... that cannot be parsed as JSON

The pipeline.separate\_logs option in [logstash.yml](https://www.elastic.co/guide/en/logstash/current/logstash-settings-file.html) may help.
