  The Secret Life of JavaScript: Illusions # javascript # coding # programming # softwaredevelopment Timothy stumbled into the West Wing of the library, blinking against the strange, shimmering light. The walls here were not lined with books, but with tall, ornate mirrors. He held a simple integer in his hand:  5 . He walked up to the first mirror to inspect it. But when he looked at the reflection, the number wasn't a sharp, mathematical  5 . It looked stretched, wrapped in quote marks. It looked like a string:  "5" . "The glass is warped!" Timothy cried, turning to Margaret, who was polishing a frame nearby. "I hold a number, but the mirror shows a word. This room is broken." Margaret didn't look up from her work. "The room is not broken, Timothy. It is  Coercive ." The Helpful Distortion (Implicit Coercion) Margaret walked over and stood beside him. "The Engine in this library is terribly polite," she explained. "If you ...

AWS API Error: REST API vs HTTP API — Why the Same Request Behaves Differently # aws # apigateway # devops # cloud How to understand and debug differences in routing, authorization, error responses, and request handling between API Gateway REST APIs and HTTP APIs when identical requests produce different results Problem You send the  same HTTP request  to two APIs in  Amazon API Gateway —one built as a  REST API , the other as an  HTTP API —and observe different behavior. Examples include: One API returns  403 Forbidden , the other returns  401 One API returns  Missing Authentication Token , the other returns  404 One API invokes the backend, the other never reaches it One API requires explicit configuration, the other “just works” From the client’s perspective, this looks inconsistent. From API Gateway’s perspective, it is expected. Clarifying the Issue Although they share a name and a console,  REST APIs and HTTP APIs are fundamentally...

  AWS API Gateway Error: “403 Forbidden” vs. “Missing Authentication Token” # aws # apigateway # devops # cloud How to determine whether an API Gateway request failed due to routing (stage, path, or method mismatch) or due to authorization (IAM, authorizers, or resource policies), and how to debug each case correctly Problem You invoke an endpoint exposed through  Amazon API Gateway  and receive  one of two errors : { "message" : "Missing Authentication Token" } —or— { "message" : "Forbidden" } Both block your request. Both sound like security issues. Only one of them actually is. Clarifying the Issue These two errors look similar but originate from  different layers  inside API Gateway. The key distinction is  how far the request made it through the system . Missing Authentication Token The request  did not match any deployed route API Gateway rejected it  before authorization Common causes: Missing or incorrect stage Incorrect r...
