Reference documentation and code samples for the Google Cloud Scheduler v1 API class AppEngineRouting.
If [service][google.cloud.scheduler.v1.AppEngineRouting.service] is empty,
then the job will be sent to the service which is the default service when
the job is attempted.
If [version][google.cloud.scheduler.v1.AppEngineRouting.version] is empty,
then the job will be sent to the version which is the default version when
the job is attempted.
If [instance][google.cloud.scheduler.v1.AppEngineRouting.instance] is
empty, then the job will be sent to an instance which is available when the
job is attempted.
If [service][google.cloud.scheduler.v1.AppEngineRouting.service],
[version][google.cloud.scheduler.v1.AppEngineRouting.version], or
[instance][google.cloud.scheduler.v1.AppEngineRouting.instance] is invalid,
then the job will be sent to the default version of the default service
when the job is attempted.
