HTTP 429 When Calling the Gemini API on AWS

Running into HTTP 429 calling the Gemini API on AWS — and how our team fixed it. Hi everyone 👋 While building our capstone project (a RAG chatbot running on EC2 that calls the Gemini API), we hit an error that anyone who’s integrated a third-party API has probably run into at least once: HTTP 429 – Too Many Requests. At first we were pretty confused, because everything ran fine locally — no signs of trouble at all. But the moment we deployed to EC2 and tested with multiple concurrent users, requests piled up and Gemini politely declined with a 429.

"Policy ArmResourceId has incorrect formatting" Has Nothing to Do With ARM Resource IDs

Policy ArmResourceId has incorrect formatting — an Azure CLI error message that cost me a whole debugging session, when the real reason was just a hyphen in the policy name. Hi everyone 👋 Setting up an Azure Front Door WAF Policy through the CLI, I ran into an error that — as it turns out — a lot of other people have been hitting for over three years, ever since it was first reported back in December 2022.
