Logstash - Error “Expected one of [ \t\r\n], ”#"

Question

I use Docker to build my Logstash 7.10.1 image, I overrided logstash.conf with :

input {
  uri => "mongodb://admin:pass@localhost:27017/programs?ssl=true"
  placeholder_db_dir => "/opt/logstash-mongodb/"
  placeholder_db_name => "logstash_sqlite.db"
  collection => "programs"
  batch_size => 5000
}

output {
  elasticsearch {
    hosts => ["http://elasticsearch-crawlers:9200"]
    index => "programs"
    document_id => "%{id}"
  }
  stdout {
    codec => rubydebug
  }
}

I have this error :

[logstash.agent ] Failed to execute action {:action=>LogStash::PipelineAction::Create/pipeline_id:main, :exception=>"LogStash::ConfigurationError", :message=>"Expected one of [ \t\r\n], "#", "input", "filter", "output" at line 1, column 1 (byte 1)", :backtrace=>["/usr/share/logstash/logstash-core/lib/logstash/compiler.rb:32:in compile_imperative'", "org/logstash/execution/AbstractPipelineExt.java:184:in initialize'", "org/logstash/execution/JavaBasePipelineExt.java:69:in initialize'", "/usr/share/logstash/logstash-core/lib/logstash/java_pipeline.rb:47:in initialize'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline_action/create.rb:52:in execute'", "/usr/share/logstash/logstash-core/lib/logstash/agent.rb:365:in block in converge_state'"]}

I am on Window, I used Notepad++ to create this logstash.conf file. I used Convert with BOM and I am on Unix (LF) format.

I don't see what is the problem here ? I checked this thread : Logstash exception Expected one of #, input, filter, output at line 1, column 1, but it seems my file is correct

Your config is missing the input plugin type, it seems that you are using the mongodb input plugin.

Your config should be something like this.

input {
    mongodb {
        uri => "mongodb://admin:pass@localhost:27017/programs?ssl=true"
        placeholder_db_dir => "/opt/logstash-mongodb/"
        placeholder_db_name => "logstash_sqlite.db"
        collection => "programs"
        batch_size => 5000
    }
}
