lambda errors: CORS policy error and then a HTTP 500 error

When you encounter CORS policy errors followed by HTTP 500 errors in AWS Lambda, address them as follows:

For the CORS Policy Error, in the API Gateway, select the resource and method, and use the "Enable CORS" feature to add the necessary CORS headers like Access-Control-Allow-Origin. Redeploy your API to apply these settings.

For the HTTP 500 Error, check CloudWatch Logs to find detailed error messages for the cause of the lambda error.

If this has answered your question or was helpful, accepting the answer would be greatly appreciated. Thank you!
