Hi All

I am facing the same issue while trying to start LS 6.5.0 on Windows 10 after a considerably long break in usage.
I have checked /pipeline_action/create.rb file to see if I could locate the missing #, but things seem fine.
Logstash logs sincedb file also deleted, but error persists.
Any help is much appreciated.

Edit:
Attempted again, this time created a basic conf file as below:

input{
stdin{}
}
output{
stdout{}
}

.. and it works!

Would still like some help to identify what's causing the error with the command line -e flag for better understanding!

Thanks!

[Dv_Thiyanesh]

i can't get you, could you can explain once again?

[Dv_Thiyanesh]

After doing this i have restarted logstash:
