GHE - self-signed TLS certs not reading correctly

[jyang-gentex]

Issue:

Skip_Checking
HttpError: request to {{https-api-path}} failed, reason: unable to verify the first certificate

Environment: Github Enterprise Server with self-signed TLS certs.

Host machine has CA root installed and is able to read correctly if manually using curl {{https-api-path}}

Is there a way to supply or specify the self-signed CA root to this action?
