JSON parse error, original data now in message field

[d6036de2b54af16665f4 (Indian)]

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

And how to find which pipeline is giving me this error.

The pipeline.separate_logs option in logstash.yml may help.
