Good day, everyone!
Today was my weekly visit to the physical therapist, so I wasn't able to code much.
I didn't really make that much progress because I was still stuck on the same problem as I was yesterday. I spent most of the time troubleshooting my AWS API Gateway integration and Lambda function. Apparently, there is something wrong with the preflight request part of the communication between frontend and backend. I used tools such as AWS CloudWatch Logs to retrieve the error message for the integration of the API Gateway.
I'm hoping that I manage to solve this issue tomorrow.
Anyway, let's move on to my daily report!
Yesterday
I set up my contact form to connect with the AWS serverless backend, but I got stuck on this bug:
Access to XMLHttpRequest at API_GATEWAY_ENDPOINT from origin http://localhost:3000 has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
I also selected a design scheme for my website.
Today
Here are the things I learned and worked on today:
Company Website
- I spent most of my time trying to solve the bug above.
- reviewed how to use CloudWatch Logs to gain insight as to what's going on with the AWS services I use.
- learned a lot about CORS.
- did a lot of searching about Access Control headers.
Scrum
- I learned about why the Daily Scrum is more than just a status report.
- I did some practice flashcards for Scrum.
- reviewed some of the things I've learned before.
Thank you for reading!
