Hi Team,

I installed GAM7 without creating a new project since I already have an existing GCP project used for GAM previously.

I ran 'gam use project' to select the existing project and OAuth client. After completing this step, I was prompted to set up a new API App in the Google Workspace admin console, trusted at the root OU.

Once that step was finished, I encountered the following error:

Project: {{GCP-Project ID}}, Service Account: {{GCP-Project ID}}, Enable Failed: Service account {{GCP-Project ID}} already exists within project projects/{{GCP-Project ID}}.

I also tried 'gam use project' with the service account email address {{service accounts email address}}, but it keeps looping. What can I do to resolve this issue?
Thanks.

Do you have the existing project client_secrets.json and oauth2service.json files?
If so, you can just use them you don't need to use: gam use project

If you don't have them, you'll have to logon to console.cloud.google.com and
download the client_secrets file, delete theesiting service account key and create a new one.

Send me a private Meet/Zoom invitation and I'll help.

Hi Ross,
Thank you for your message.
No, I don't have access to the existing files because I had to rebuild the laptop without backing them up. I will try deleting the current service account key and creating a new one.

I'll update you on my progress.
By the way, what's your preferred time to catch up and your timezone?
Thank you.
