Hi,
The CORS error is a secondary error caused by a previous error of a missing package (aws-xray-sdk-core) in AWS Lambda.
Generate local installation of all packages (libraries) and then deploy them together in AWS Lambda.
When checking the CloudWatch logs of the AWS Lambda functions It can be seen the error of a missing package/library aws-xray-sdk-core
:

]
}
Currently the AWS Lambda functions only require/depend on these 3 packages:
"aws-sdk": "^2.823.0",
"aws-embedded-metrics": "^2.0.2",
"aws-xray-sdk-core": "^3.2.0"
The aws-sdk
seems to be already included in AWS Lambda (no error about it). However, the xray library seems to be missing (or there is some internal bug).
I tested with NodeJS 14 version of AWS Lambda and the xray library was not available there either.
I did npm install
inside the todo-src\getAllTodo
folder then did another sam deploy
and it was fine.
The CORS error disappeared.
I created a bash script to do the install of the libraries in all function folders:
cd todo-src/
cd addTodo; npm install; cd ..
cd completeTodo; npm install; cd ..
cd deleteTodo; npm install; cd ..
cd getAllTodo; npm install; cd ..
cd getTodo; npm install; cd ..
cd updateTodo; npm install; cd ..
cd ..
1) Check with the AWS Lambda team on why the aws-xray-sdk-core
library is not available.
2) Furthermore, it will be useful to expand/update this page: https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html and give detailed list of all libraries/packages and their version supported by AWS Lambda.
3) Deploying the whole installation of packages is not user friendly as the code gets zipped and is not visible in AWS portal.

Hello,
After deploying the webapp, when I sign up and then login, the page that is in the screenshot (attached) appears briefly then I get redirected to the login page again.
This seem to be an issue with the CORS policy, do you know how I can solve this?
Thank you!
