Navigating CORS Errors and AWS API Gateway Challenges - Ep 175
2In this video, I tackle a challenging debugging session as we attempt to fine-tune cross-origin resource sharing (CORS) settings while integrating AWS API Gateway with Lambda functions for our project. We dive into solving CORS preflight issues, explore API Gateway V2 documentation, and troubleshoot deployment nuances step by step.
You'll see how I approach common issues such as:
Working through errors like 'CORS missing allow origin'.
Setting up default authorizers and analyzing options for specific routes.
Investigating HTTP response codes (401, 204) and their implications within the API Gateway ecosystem.
Implementing Lambda integrations, permissions errors, and understanding resource policies.
The session includes live debugging, reading API Gateway documentation, and iterating on code deployments to identify potential solutions. By the end of the stream, we make progress on resolving some issues while noting areas that need further exploration. It’s a great hands-on learning experience if you’re working with AWS API Gateway, Lambda, or tackling CORS-related problems in your cloud projects.
