Returns the URL-encoded service path of the service, for example "tasks/v1/".

or a forward slash "/", if it is a forward slash then it is treated as an empty string
Universe Domain is the domain for Google Cloud Services. It follows the format of
{ServiceName}.{UniverseDomain}. For example, speech.googleapis.com would have a Universe
Domain value of googleapis.com and cloudasset.test.com would have a Universe Domain of
test.com. If this value is not set, this will default to googleapis.com.
Check that the User configured universe domain matches the Credentials' universe domain. This
uses the HttpRequestInitializer to get the Credentials and is enforced that the
HttpRequestInitializer is of the {@see HttpCredentialsAdapter}
from the google-auth-library.
To use a non-GDU Credentials, you must use the HttpCredentialsAdapter class.
