Hello,

I am running into a problem during the Elastic Observability Engineer training;

I am trying to verify the heartbeat configuration and I get the following:

(elastic) elastic@ip-172-31-0-129:~/heartbeat$ ./heartbeat test config  
Exiting: error initializing publisher: 1 error: open /home/elastic/ca/ca.crt: no such file or directory reading accessing 'output.elasticsearch' (source:'heartbeat.yml')

/home/elastic/ca/ca.crt not in place?

Please help.

Best regards,  
John
