Hello, I’m hoping to get some help with a persistent blocker on my Google Cloud account. My project is consistently blocked by a `429 Quota Exceeded` error on the very first API call to the Vertex AI embedding model, and I believe it’s an account-level issue. **Project Context:** The project, “Project Haystack,” is an internal AI search engine to index our company’s unstructured data from Gmail and Zoom transcripts using the `gemini-embedding-001` model and Vertex AI Vector Search. **The Problem & Troubleshooting:** When we run our Python script, it fails on the very first API call with a `429` error and gets stuck in a retry loop. We have already done extensive troubleshooting and confirmed: * The **Vertex AI API** is enabled. * The project is linked to an **active billing account**. * The Quotas page shows a high limit (**5,000,000 tokens per minute**). * The error occurs in **multiple regions**. * Most importantly, the error persists even in a **brand new Google Cloud project** created from scratch. Because the error occurs even in a fresh project with a confirmed high quota, we are certain this is a deeper, non-visible limit or a backend provisioning issue with my account that is preventing it from using the service. Could a community manager please help investigate why my account is blocked from using its assigned quota? Thank you.
