Manual sync request: "Error during billing setup" - Paid but stuck on Free trial

Hello, I have successfully added a payment method and funded my Google Cloud Billing account, but my project is stuck on the "Free trial" tier. When I click the "Activate billing" button in AI Studio, I get a popup saying "Error during billing setup" and a system error. My Project ID is: gen-lang-client-023377033… Please manually synchronize the billing status for my project so my API key can use the Pay-as-you-go limit. Thank you.

Hello @Anh_Duc_Vu ,

DM’ed you for more details.

Hello @Anh_Duc_Vu ,

Are you still facing this error? if yes,

To help us investigate the exact error, could you please share a browser network recording (HAR file)? This will allow us to inspect the underlying API request and error response returned when you click the button.

Steps to capture the HAR file:

  1. In Google AI Studio, open Developer Tools by pressing F12 (or right-click anywhere on the page and select Inspect).
  2. In the Developer Tools panel, switch to the Network tab.
  3. Check the Preserve log checkbox.
  4. Reproduce the issue by clicking Set up prepay (or triggering the error).
  5. Once the error appears, right-click anywhere in the list of network requests and select Save all as HAR with content (or click the Export HAR download icon).
  6. Share the saved .har file with us here (or via private message).

(For additional details, see the Google Cloud guide on capturing browser traces.)
