AWS SAM Template: API Gateway Deployment scenarios with 'Missing Authentication Token'
I'm having a hard time understanding I'm prototyping a solution and I've hit a wall trying to I've spent hours debugging this and I'm working with an scenario when deploying my AWS SAM application that includes an API Gateway. After deploying successfully, I attempt to access the API endpoint but receive a 'Missing Authentication Token' behavior. My SAM template has the following configuration: ```yaml AWSTemplateFormatVersion: '2010-09-09' Transform: AWS::Serverless-2016-10-31 Description: My SAM Application Resources: MyFunction: Type: AWS::Serverless::Function Properties: Handler: app.lambda_handler Runtime: python3.8 Events: Api: Type: Api Properties: Path: /myresource Method: get ``` I've deployed the stack using the command `sam deploy --guided`, and the endpoint provided after deployment is something like `https://abc123.execute-api.us-east-1.amazonaws.com/Prod/myresource`. However, when I make a GET request to this URL (e.g., using Postman), I always get the 'Missing Authentication Token' response. I have also confirmed that the API Gateway is indeed deployed and that the AWS Lambda function is set to the correct permissions. However, I suspect there might be an scenario with how the path is defined or how I'm constructing the request. Here are a couple of the things I've tried: 1. Checking if the correct stage is specified in the URL. I made sure to use `/Prod/myresource`. 2. Verifying that the AWS Lambda function is correctly set up to respond to the `GET` method. 3. Looking into the API Gateway settings in the AWS console, but everything seems to be in order. Has anyone else run into this scenario? Are there specific configurations or best practices I might be missing related to API Gateway paths and deployment? Any insights would be greatly appreciated. I'm working on a web app that needs to handle this. I appreciate any insights! For context: I'm using Yaml on Windows 11. Any pointers in the right direction?
