AWS API Gateway with Lambda Proxy Integration Returns 403 Forbidden on POST Request
I'm trying to implement I'm currently working with a `403 Forbidden` behavior when trying to access my AWS Lambda function via API Gateway with proxy integration. My setup involves a simple Node.js Lambda function that is supposed to handle a POST request from an API Gateway endpoint, but it seems that the permissions are not configured correctly. Here's a snippet of my Lambda function: ```javascript exports.handler = async (event) => { console.log('Received event:', JSON.stringify(event, null, 2)); const response = { statusCode: 200, body: JSON.stringify('Hello from Lambda!'), }; return response; }; ``` In API Gateway, I've configured everything to use Lambda proxy integration, but I'm getting the `403 Forbidden` response when I try to execute a POST request. I have verified the following: - The API Gateway endpoint is deployed. - The resource and method permissions are set to allow access. - The IAM role associated with my Lambda function has the `AWSLambdaBasicExecutionRole` policy attached. - CORS is enabled on the API Gateway for the POST method. Here is how I defined my API Gateway method: - Resource: `/myresource` - Method: `POST` - Integration type: `Lambda Function` - Use Lambda Proxy integration: `Yes` Despite checking these configurations, the scenario continues. I also tried adding an execution role with the `AWSLambdaRole` policy, but that didn’t change the outcome. The logs show that there are no issues with the execution of the Lambda function itself, as they indicate that the function is invoked correctly but never reaches the execution. Could anyone provide insights into what might be misconfigured or what further diagnostics I could perform to resolve this scenario? I appreciate any help! I'm coming from a different tech stack and learning Javascript. Hoping someone can shed some light on this. Thanks in advance! Any feedback is welcome!
