The error message you're seeing suggests that you're trying to access Databricks on Google Cloud Platform (GCP) without a valid token from the GCP Marketplace. To resolve this, you need to start over from the GCP Marketplace portal and make sure you have a valid token. Here are the steps you need to follow:
1. Create your Databricks subscription in Google Cloud Marketplace. This step creates a Databricks account. As the account owner, you are the only one who can perform the initial setup.
2. Create at least one Databricks workspace. A workspace is the environment that your team will use to access all of their Databricks assets.
3. Add users and groups to your workspaces.
Before you start, make sure you have the following:
- A Google billing account
- The necessary roles for Google Identity and Access Management (IAM): Billing Administrator (roles/billing.admin) for the target Cloud Billing account or the Google Cloud organization where your project is located, and Viewer (roles/viewer) for the project associated with the billing account you plan to use.

If you don't have these roles, contact the respective administrators to request access. If you create a new project, ensure you enable billing and link the project to the desired Cloud Billing account.
