Run sdk-doctor with certificate authority

Hi All.
How can I test the connection to the couchbase server using SDK-doctor and certificate authority?
I know that command is

sdk-doctor diagnose couchbase:// -a path/to/file

But I don’t know what type of file using to check to connect?
In addition, how can I use the JKS file as a param? Because I only have 2 jks files check to connect: rootCA.jks / travel-sample.jks
