Hi everyone,
im having some issue with docker and logstash. I have the following error:

2023-10-03 14:46:24 warning: thread "[main]-pipeline-manager" terminated with exception (report_on_exception is true):

It looks like i don't have the file net/smtp, i have checked from the files and i cant find it.
Im using logstash on docker with WSL2.

Thank you in advance

This is a bug on version 8.10.X, it is being tracked here.

You should use rollback to version 8.9.
