Hi I will launch Logstash on the basis of [this tutorial](https://github.com/elastic/examples/tree/master/Common%20Data%20Formats/twitter), but I encounter the following error I use current version of logstash on windows server 2008. ``` C:\elk\logstash>.\bin\logstash -f logstash.conf ``` Sending Logstash's logs to C:/elk/logstash/logs which is now configured via log4j2.properties [2018-02-14T11:35:45,925][INFO][logstash.modules.scaffold] Initializing module {:module\_name=\>"fb\_apache", :directory=\>"C:/elk/logstash/modules/fb\_apache/configuration"} [2018-02-14T11:35:45,956][INFO][logstash.modules.scaffold] Initializing module {:module\_name=\>"netflow", :directory=\>"C:/elk/logstash/modules/netflow/configuration"} [2018-02-14T11:35:46,550][WARN][logstash.config.source.multilocal] Ignoring the 'pipelines.yml' file because modules or command line options are specified [2018-02-14T11:35:47,628][INFO][logstash.runner] Starting Logstash {"logstash.version"=\>"6.2.1"} [2018-02-14T11:35:48,410][INFO][logstash.agent] Successfully started Logstash API endpoint {:port=\>9600} [2018-02-14T11:35:48,981][ERROR][logstash.agent] Failed to execute action {:action=\>LogStash::PipelineAction::Create/pipeline\_id:main, :exception=\>"LogStash::ConfigurationError", :message=\>"Expected one of #, input, filter, output at line 1, column 1 (byte 1) after ", :backtrace=\>["C:/elk/logstash/logstash-core/lib/logstash/compiler.rb:42:in `compile_imperative'", "C:/elk/logstash/logstash-core/lib/logstash/compiler.rb:50:in`compile\_graph'", "C:/elk/logstash/logstash-core/lib/logstash/compiler.rb:12:in `block in compile_sources'", "org/jruby/RubyArray.java:2486:in`map'", "C:/elk/logstash/logstash-core/lib/logstash/compiler.rb:11:in `compile_sources'", "C:/elk/logstash/logstash-core/lib/logstash/pipeline.rb:51:in`initialize'", "C:/elk/logstash/logstash-core/lib/logstash/pipeline.rb:169:in `initialize'", "C:/elk/logstash/logstash-core/lib/logstash/pipeline_action/create.rb:40 :in`execute'", "C:/elk/logstash/logstash-core/lib/logstash/agent.rb:315:in `block in converge_state'", "C:/elk/logstash/logstash-core/lib/logstash/agent.rb:141:in`with\_pipelines'", "C:/elk/logstash/logstash-core/lib/logstash/agent.rb:312:in `block in converge_state'", "org/jruby/RubyArray.java:1734:in`each'", "C:/elk/logstash/logstash-core/lib/logstash/agent.rb:299:in `converge_state'", "C:/elk/logstash/logstash-core/lib/logstash/agent.rb:166:in`block in converge\_state\_and\_update'", "C:/elk/logstash/logstash-core/lib/logstash/agent.rb:141:in `with_pipelines'", "C:/elk/logstash/logstash-core/lib/logstash/agent.rb:164:in`converge\_state\_and\_update'", "C:/elk/logstash/logstash-core/lib/logstash/agent.rb:90:in `execute'", "C:/elk/logstash/logstash-core/lib/logstash/runner.rb:348:in`block in execute'", "C:/elk/logstash/vendor/bundle/jruby/2.3.0/gems/stud-0.0.23/lib/stud/task.rb:24:in `bl ock in initialize'"]} my config file input { twitter { consumer\_key =\> "\_\_\_iQIzkm4F7GjDkyCHCiQ" consumer\_secret =\> "\_\_\_eRtIVg6IrspojErEi3Q7bCzlnCegXTZgq2KG8cfE" oauth\_token =\> "\_\_\_199358-XJlYRF6ZEFnor8xHhwyDrBQodtKOw8b8EabX3zPa" oauth\_token\_secret =\> "\_\_\_l06hmNmdCVyO0S6pbfoTlJqDc0qNIbywe6ucMjkeKT" keywords =\> ["thor", "spiderman", "wolverine", "ironman", "hulk"] full\_tweet =\> true } } filter {} output { stdout { codec =\> dots } elasticsearch { hosts =\> "localhost:9200" index =\> "twitter\_elastic\_example" document\_type =\> "tweets" template =\> "./twitter\_template.json" template\_name =\> "twitter\_elastic\_example" template\_overwrite =\> true } } ---

Wild guess: You edited the configuration file with an editor that put a byte-order mark at the very beginning of the file. Make sure your configuration file _really_ begins with an "i". ---

@magnusbaeck thanks for your reply. I change Encoding of config file from UTF-8 to ANSI and now work well! ---
