Error generating a custom certificate and private key for Fleet Server

[Lelc79 (Luis)]

Hi Elastic community

I am generating my certificates to my Fleet Server

Step1
./bin/elasticsearch-certutil ca --pem

i moved my CA.cert & ca.key to /path/to/ca

Step2:

./bin/elasticsearch-certutil cert
--name FleetSrv
--ca-cert /path/to/ca/ca.crt
--ca-key /path/to/ca/ca.key
--dns ABC.DOMAIN.COM
--ip 192.0.1.20
--pem

Error

Exception in thread "main" java.nio.file.NoSuchFileException: /path/to/ca/ca.crt
