Logstash not parsing metadata from logfile

[Badger]

I would parse each line with a separate pattern

grok {
    break_on_match => false
    match => {
        "message => [
            "method: (?<method>[^\n]*)",
            "userId: (?<userId>[^\n]*)",
            "jobId: (?<jobId>[^\n]*)",
            ...
        ]
    }
}
