JSON output prepended with non-JSON data

[tsvallender]

In my application.rb I have:

    config.semantic_logger.add_appender(io: $stdout, formatter: :json)
    config.log_level = :info
    SemanticLogger.add_appender(appender: :new_relic)

And an example line from my logs is now:

2025-01-27 20:16:35.037614 I [1:puma srv tp 001] (12.2ms) CspReportsController -- Completed #create -- { :controller => "CspReportsController", :action => "create", :format => "*/*", :method => "POST", :path => "/csp-reports", :status => 200, :view_runtime => 0.0, :db_runtime => 17.08, :queries_count => 1, :cached_queries_count => 0, :allocations => 2198, :status_message => "OK" }

I wasn’t expecting the initial 2025-01-27 20:16:35.037614 I [1:puma srv tp 001] (12.2ms) CspReportsController -- Completed #create -- — I thought this data should be converted to JSON. Is this the intended behaviour? Is there a way I can get “pure” JSON output?

Hi mate!
I believe you need something like this:

That’s done it, thank you 🙏
