Paid Tier 1 but "Set up prepayment" fails with "System error" — cannot fund Prepay (billing account 009DA2-713DFD-699..)

Hello,

My project is on Paid Tier 1 but I cannot set up or fund the Prepay wallet, so
the Gemini API cannot be used at all. Posting the exact details, since I’ve seen
other users hit the same wall and that a HAR file from the failing click is what
is needed to investigate.

CURRENT STATE

  • Billing account: “Conta eduvm” — ID 009DA2-713DFD-6990..
  • Linked project: “Quase Organico” — ID gen-lang-client-09823641..
  • AI Studio Billing page shows: “Paid 1 — US$ 250 account-level limit”, 1 project
  • The same page shows: “US$ 10 qualified GCP credits”
  • The same page also shows: “No prepayment method has been configured for this
    billing account. Prepayment is required for this billing account.”

THE FAILURE

Clicking “Set up prepayment” immediately returns:

System error.
Something went wrong. We're working to restore the service as quickly as
possible. Close this window and try again in a few minutes.

The setup flow never opens. Without a prepaid balance there is no way to use the
paid API, so the account is stuck.

WHAT I HAVE ALREADY TRIED

  • Verified in Cloud Console that the billing account is active with a valid
    payment method attached
  • Confirmed the project is correctly linked to that billing account
    (billingEnabled = true)
  • Clicked “Set up prepayment” several times, on different days
  • Tried from the AI Studio Billing page
  • Tried in an incognito window with all extensions disabled — same “System
    error”, so this is not a local browser or extension issue

WHAT I AM ASKING FOR

Could someone please inspect the billing state of this account and project on
the backend? I am happy to purchase the prepaid credits — the problem is that
Google’s own interface will not let me complete the Prepay setup. Please don’t
send me back to the “Set up prepayment” button, since that button is precisely
the part that is failing.

I can capture a sanitized HAR file of the failing click and provide screenshots
of the “Paid 1” status, the “no prepayment configured” message and the System
error — just ask and I will attach them.

Thank you.

Hi, can you please try to redo the steps again and capture a HAR file and share the HAR file with us?

Steps to Record and Export a HAR file

  • Open Google Chrome and go to the web page where you are having an issue.
  • Open Developer Tools by pressing F12 or Ctrl+Shift+I (Windows/Linux), or Cmd+Option+I (Mac). Alternatively, click the three vertical dots menu, go to More tools, and select Developer tools.
  • Click on the Network tab in the top panel.
  • Look at the top-left corner of the Network tab for a round Record button and make sure it is red. If it is gray, click it once to start recording.
  • Check the box for Preserve/ Keep log to save network traffic across page reloads and redirects.
  • Reproduce the issue by repeating the actions that caused the problem.
  • Click the Export HAR download icon (or right-click anywhere in the request table and choose Save all as HAR with content or Copy > Copy all as HAR and then save in a file).

Thanks!
