Permission Issues Accessing sdm-prod Project Resources

[johnhuetz]

Problem Description

I am encountering permission issues with the homebridge-google-nest-sdm plugin. The plugin initialization fails due to lack of access to the sdm-prod project. The specific errors indicate missing permissions for pubsub.topics.get and serviceusage.services.list.

Steps to Reproduce

1. I set up the plugin according to the provided documentation, including adding the additional scope when obtaining the authorization code.
2. I confirmed that the Smart Device Management and Pub/Sub APIs are enabled.
3. I obtained the OAuth credentials and refresh token as instructed.
4. Upon running Homebridge, the plugin logs show errors related to permission issues with the sdm-prod project.

Expected Behavior

The plugin should initialize successfully and connect to my Google Nest devices without requiring access to the sdm-prod project.

Actual Behavior

The plugin initialization fails with the following error message:

'Plugin initialization failed, there was a failure with event subscription. StatusError: Requested project not found or user does not have access to it (project=sdm-prod)'

Additional Context

• I have verified that my Google Cloud and Device Access Console projects are correctly linked.
• My account has Owner permissions on my Google Cloud project.
• There seems to be a misconfiguration that causes the plugin to attempt to access the 'sdm-prod' project, which I do not have permission for.

Question

How can I configure the plugin to avoid permission issues with the 'sdm-prod' project? Is there a step I missed that grants my Google account the necessary permissions, or should the plugin reference resources only within my Google Cloud project?

Hi @johnhuetz, since many thousands of people have setup the plugin without this problem I think it is not an issue with the plugin but probably your configuration, so I've converted it to a discussion. Remember your subscription ID field should look like "projects/your-gcp-project-id/subscriptions/your-subscription-id", if you "sdm-prod" where "your-gap-project-id" goes then you've got the wrong URL.

Thanks, @potmat, for moving my "issue" to a discussion; I should have done that from the get-go !

I used just the subscription ID vs. the full subscription name in the config setting, a total amateur move.

I see my Nest cameras now in the apple Home app, but no video stream, but I'll keep working on it. Thanks again for the help!
