Error while starting Log Stash Expected one of [ \\t\\r\\n]

Connecting LogStash to SQL Server. Could help me with following error while starting logstash?

I executed this command:

logstash.bat -f c:\DevSoft\logstash-8.3.3\bin\logstash-sample.conf

I get following error: I tried removing all whitespaces from .conf file but with no luck.

[ERROR][logstash.agent ] Failed to execute action {:action=>LogStash::PipelineAction::Create/pipeline_id:main, > :exception=>"LogStash::ConfigurationError", :message=>"Expected one of [ \t\r\n], "#", "if", [A-Za-z0-9_-], '"', "'", "}" at line 1, column 8 (byte 8) after input {",

Here is logstash-sample.conf located in bin folder itself where logstash.bat is:
