JVM (e.g. java -version):
Since we are installing logstash through docker, we have not installed jdk on our hosted vm.
I am providing the base image jdk version which is used by docker logstash internally:

1. JVM version: openjdk version "11.0.7" 2020-04-14 LTS
2. JVM installation source:
   OpenJDK Runtime Environment 18.9 (build 11.0.7+10-LTS)
   OpenJDK 64-Bit Server VM 18.9 (build 11.0.7+10-LTS, mixed mode, sharing)
3. Value of the LS_JAVA_HOME environment variable if set: Not set

OS version (uname -a if on a Unix-like system): Host os version = CentOS 8.1

Description of the problem including expected versus actual behavior: If the indentation is not provided properly in pipelines.yml file is not provided properly, logstash is not throwing correct error. It should throw some validation error or some other error though which we can identify there is some problem in configuring pipelines.

Steps to reproduce:

Please include a minimal but complete recreation of the problem,
including (e.g.) pipeline definition(s), settings, locale, etc. The easier
you make for us to reproduce it, the more likely that somebody will take the
time to look at it.

1. Edit pipelines.yml file and intentionally put wrong indentation for one of the pipelines.
2. Restart logstash
3. Check for logstash logs. The error thrown is not conveying correct information.

Provide logs (if relevant):
