Vertex AI DataStore unable to Index Google Drive Shared Drive

Hi Everyone,

I am trying to train a Vertex AI Search app based on data from a shared drive in my organization’s google drive via the AI Applications → Data Stores page. However, the drive never seems to get indexed and thus the search model I’m trying to create never returns any results. The datastore shows as active and the drive connector is successfully created.


The number of documents in my drive entity is shown as a dash “-” despite what I believe to be proper configuration, I have:

  • Granted the Vertex AI Service Agent read access to my shared drive
  • The service agent has the Discovery Engine Admin role at the project level
  • Google Identity is configured as the identity provider for the Vertex AI app
  • My account has Manager Permissions on the shared drive in question
  • The Shared drive has documents of valid size/format in it
  • Billing set up on the Workspace
  • I checked my quotas and I am well within the range for my organization

I checked the Cloud Logging and see that the the data connector is successfully created when I make my datastore and do not see any error messages so I’m not sure why my shared drive is not being indexed. I’ve tried remaking the datastore and the Vertex AI Search Agent several times, as well as adding/changing documents in my drive to try to trigger an index with no luck.

How should I go about solving this issue? Am I missing something or is this a behind-the-scenes issue that I’m unable to address myself?

Any help is appreciated!
Sam
