Logstash Configuration Error: Compiler Failure and Pipeline Initialization Issue

There seems to be an error in the Logstash configuration file. The backtrace shows that the compiler was unable to compile the sources, which led to the pipeline initialization failing. It is recommended to check the configuration file for any syntax errors or invalid settings.
