how to find GCP services interdependencies - google-cloud-platform

Question

Before I can use a particular service, I have to enable the API in my Google project. Sometimes when I do this, more services are enabled than the one I specified. for example, enabling cloudfunctions service actually enabling multiple APIs in the background like pubsub, storage etc.
I followed this article to find the service dependencies https://binx.io/blog/2020/10/03/how-to-find-google-cloud-platform-services-dependencies/. The command output in the above article shows the dependent services as below
gcloud services list \
--available --format json | \
jq --arg service cloudfunctions.googleapis.com \
'map(select(.config.name == $service)|
{
name: .config.name,
dependsOn: .dependencyConfig.dependsOn
}
)'
the result is:
{
"name": "cloudfunctions.googleapis.com",
"dependsOn": [
"cloudfunctions.googleapis.com",
"logging.googleapis.com",
"pubsub.googleapis.com",
"source.googleapis.com",
"storage-api.googleapis.com",
"storage-component.googleapis.com"
]
}
when i am executing this command, i am not getting the output as above. the ""dependsOn":" section is showing as "null"
below is the output of the same command when i executed in cloudshell.
{
"name": "cloudfunctions.googleapis.com",
"dependsOn": null
}
]
does there any alternate way to identify the service interdependencies. can someone help on this please

I do not see the dependencyConfig section output by the command on my system.
When I look at the API documentation, the Service resource does not contain the section dependencyConfig.
It appears that Google has removed that item from the API that the command gcloud services list uses to display service information.
